    There seems to be a problem with the final tests in Rust (spelling?):

    basics_rank
assertion failed: `(left == right)`
  left: `"William"`,
 right: `"Willaim"`

    please explain the condition of the task If it is clear where the winning numbers come from, then why in the 2nd example, with n = 4, Paul won

    Nice kata!

    I think there is a problem with the button ATTEMPT for passing the complete set of 51 random tests. My code usually passes most of the random tests except 3 or 5 . Usually, the error displayed is “expected Elizabeth to equal Matthew.” On the other hand, when I manually compute the winning numbers from Elizabeth and Matthew, they are different. The same happens with the other errors. I suggest to review the random tests.

    In OCaml, we seems to have more elements than people. Which is not specified in the description and cause an error when doing we traversal to compute score.

    I think there's an issue with the final fixed tests for PowerShell. I'm not doing any manipulation on character order yet some have either the test case or the value passed in as $st that are misspelled.

    [2] Expected strings to be the same, but they were different.
String lengths are both 7.
Strings differ at index 4.
Expected: 'Willaim'
But was:  'William'
           ----^
[3] Expected strings to be the same, but they were different.
String lengths are both 6.
Strings differ at index 4.
Expected: 'Olivia'
But was:  'Olivai'
           ----^

    There is a problem with the tests. 4 in 104 fail and in all these cases it does not comply with the instruction: "When two people have the same winning number sort them alphabetically by their firstnames."

    The cases are:

    Log names: Elijah,Chloe,Elizabeth,Matthew,Natalie,Jayden weights: [1, 3, 5, 5, 3, 6] n:2 dat = Any["Matthew" "Elizabeth" "Jayden" "Natalie" "Chloe" "Elijah"; 485 485 390 207 144 51] winnums = Any[485, 485, 390, 207, 144, 51] key = 485 posall = [1, 2] outnames = SubString{String}["Matthew", "Elizabeth"] Actual Elizabeth Expect Matthew

    Log names: Lily,Lagon,Olivai,Emily,Madison,Olivia,Matthew,Noah weights: [6, 1, 2, 4, 1, 2, 3, 4] n:6 dat = Any["Lily" "Matthew" "Emily" "Noah" "Olivia" "Olivai" "Madison" "Lagon"; 372 291 276 168 148 148 82 54] winnums = Any[372, 291, 276, 168, 148, 148, 82, 54] key = 148 posall = [5, 6] outnames = SubString{String}["Olivia", "Olivai"] Actual Olivai Expect Olivia

    Log names: Alexander,Robert,Sophia,Michael,Lily,Samantha,Emily weights: [2, 1, 3, 3, 3, 4, 5] n:5 dat = Any["Emily" "Samantha" "Sophia" "Lily" "Alexander" "Michael" "Robert"; 345 340 222 186 186 174 84] winnums = Any[345, 340, 222, 186, 186, 174, 84] key = 186 posall = [4, 5] outnames = SubString{String}["Lily", "Alexander"] Actual Alexander Expect Lily

    Log names: Ella,Ella,Joshua,Samantha,Olivia,Madison,Sofia,Noah,Mason,Avery,David,Isabella,Olivai,Lily weights: [1, 4, 1, 5, 4, 3, 3, 5, 2, 3, 4, 5, 4, 5] n:5 dat = Any["Samantha" "Isabella" "Lily" "Olivai" "Olivia" "Madison" "Avery" "Noah" "David" "Sofia" "Ella" "Mason" "Joshua" "Ella"; 425 345 310 296 296 246 228 210 180 165 136 134 80 34] winnums = Any[425, 345, 310, 296, 296, 246, 228, 210, 180, 165, 136, 134, 80, 34] key = 296 posall = [4, 5] outnames = SubString{String}["Olivai", "Olivia"] Actual Olivai Expect Olivia

    Good kata, problem description was clear but structured poorly. Read through it and look at the tests to help understanding, if you are having trouble be descriptive in your variable names.

    This kata is purposefully tricky rather than poorly written. I recommend giving it another shot rather than dismissing it immediately.

    Rust tests need to verify return type, otherwise my solution works (return Cheat type, which equals everything).

  • sztssp Avatar

    I read and read and reread the first few lines of instructions and then just gave up. Too bad it seems like a nice puzzle for sorting. It just promises to take too long to decipher a broken description

  • Larsa Avatar

    I quite enjoyed this kata. For me perhaps a little more difficult than most other 6kyu I have done. Pays to read the instructions carefully as I omitted to include the string length in my calcuations and sat looking and wondering why my solution was incorrect.

    The tests fail on Codewars:

    " Test Failed actual not equal to expected. 'current' is not a factor "

    When I use "testthat" and run the exact same code in Rstudio, it works fine.

  • TobiasR Avatar

    Uh, these special edge cases were killing it for me. Still thanks for the training!

  • MrAras7 Avatar

    The test cases are inconsistent.

    The first sample shows the first name which comes last is winner when there's tie in final points.

    NAMES :[Elijah, Chloe, Elizabeth, Matthew, Natalie, Jayden] WEIGHTS :[1, 3, 5, 5, 3, 6] THEIR SCORE :[51, 144, 485, 485, 207, 390] WINNER :2 FINAL CONTESTERS:[Elizabeth, Matthew] expected:<[Matthew]> but was:<[Elizabeth]>

    But the second is opposite of sample 1. NAMES :[Aubrey, Olivai, Abigail, Chloe, Andrew, Elizabeth] WEIGHTS :[3, 1, 4, 4, 3, 2] THEIR SCORE :[234, 74, 192, 192, 213, 194] WINNER :4 FINAL CONTESTERS:[Abigail, Chloe] expected:<[Abigail]> but was:<[Chloe]>

if n > len(names): return "Not enough participants"
som_names = []
alp_ranks = {chr(rank): rank - 96 for rank in range(97, 123)}

for name in names:
    som = (sum([alp_ranks[letter.lower()] for letter in name]) + len(name)) * we.pop(0)
    som_names.append([som, name])

som_names = sorted(som_names, key=lambda x: x[1], reverse=False)
som_names = sorted(som_names, key=lambda x: x[0], reverse=True)

  • marjan Avatar

    Quite complicated Kata. There you have to find out relation between unsorted and sorted array's indexes. Because you need it when you have to rearrange the string array.

  • bugdent Avatar

    The part people get confused at is picking the score at n, then picking the first name from a seperate sorted array of participants with that score. The name sorting is more like a tie breaker. For example if "a", "b", and "c" are tied for 3rd, b would be 4th. So if n is 4 you wouldn't be picking a, you would pick b.

  • laytone Avatar

    Hope this doesn't get marked as spoiler. If you're having issues dealing with ties, this is something i wish i had found out earlier.

    Dealing with ties by sorting in alphabetical order is mandatory it has to be done always.

    The problem is that the instructions read that IF there is a tie with the prize winner, this has to be solved by sorting in alphabetical order, but this has to be done regardless two people having the same winning number. Hope this helps

  • dcordell Avatar

    Can anyone explain to me (Javascript) when I try to return a property on an object with index n-1, it returns undefined in codewars but works correctly in all browser consoles?

    See information below for context:

    n = 4

    0 { name: "Addison", winningNum: 292 } ​ 1 { name: "Michael", winningNum: 232 } ​ 2 { name: "Andrew", winningNum: 213 } ​ 3 { name: "Benjamin", winningNum: 152 } ​ 4 { name: "Jayden", winningNum: 130 } ​ 5 { name: "Lily", winningNum: 62 } ​ 6 { name: "Sofia", winningNum: 55 }

    returning the object.name property with the the index [n] works... [n -1], however, (Since rank starts at 1) returns undefined. Perhaps not the best way to solve the problem, but I'm a bit perplexed why this is happening...

    Any insight? Thanks :)

  • MacirBrustolin Avatar

    Way harder to understand than should be

  • celiackelly Avatar

    I created a 2D array with the names of the participants and their winning numbers in descending order.

    let sorted = [ [ 'Addison', 348 ], [ 'Michael', 288 ], [ 'Andrew', 249 ], [ 'Benjamin', 184 ], [ 'Jayden', 154 ], [ 'Lily', 70 ], [ 'Sofia', 65 ] ]

    For the first test case where n=4 and the winner is Benjamin, I am trying to return sorted[n - 1][0], I get the error that it can't access the property [0] of undefined. However, when I console log this expression, it works just fine and prints 'Benjamin.' Also, the return statement works just fine in VSCode.

    I haven't dealt with the instances where the string is empty or n is greater than the number of participants yet.

    function rank(names, weights, n) { const calcSom = (name) => name.toLowerCase() .split('') .reduce((sum, ch) => sum + (ch.charCodeAt(0) - 94), 0) + name.length

    const winningNums = names.split(',')
                       .map((name, i) => calcSom(name) * weights[i])

let namesAndNums = names.split(',')
                        .reduce((arr, name, i) => {
                           arr[i] = [name, winningNums[i]]
                           return arr
                          }, [])

let sorted = namesAndNums.sort((a, b) => b[1] - a[1] || b[0] - a[0])

console.log(sorted)

//The winner is at index n-1, because the position n is not zero-indexed. This console.log() statement works fine and gives the correct winner, 'Benjamin'
console.log(sorted[n - 1][0])

//BUT the return statement yields undefined on CodeWars. But it works fine in VSCode!
return sorted[n - 1][0]

    }

    Solved this one in ReasonML — thanks again for another kata that... was much more of a faff to complete than it had any right to be 😆! Still, at least I'm getting better at Reason / OCaml, which I seem to be finding hard mostly because of the inflexibility of the types in the standard library (I'd just like to use one map for everything, dammit!)

    I really appreciate, g964, that you have translated this kata to Reason, as you're seemingly the only author to have uploaded any Reason-language kata at all. Thanks!

  • kbanach Avatar

    The description of this kata is a terrible mess... Please rewrite it in actual English without the story. Just keep it simple: what is the input, what is the output and why. Currently there is "PauL" used as an example, which causes more questions than given answers. Subjectively that's the most unclear kata that I did since now.

  • julianchso Avatar

    Can someone help me? I'm doing it in javascript. This is the test I'm failing, which I'm assuming is due to sorting alphabetically.

    expected 'Elizabeth' to equal 'Matthew'

    What data structure should I use?

    My pseudocode: I store everything in an object where key is the name, value is the score. I also store the score in an array since object is unordered. I then sort the array, which I use the value (score) to find the key in the object.

    Doesn't really work when the score is the same.

    I really enjoyed this kata though. For a beginner like me, it's challenging enough and not so easy where I can solve with 2 loops but still think it's doable.

    Hmm I thought that E is before I

  • kaledoux Avatar

    I can't seem to pass the test case where Matthew and Elizabeth are supposed to evaluate to the same total value, and thus be sorted alphabetically. My issue here is that those two names don't amount to the same total value. I tore my logic apart and went through the hard way, matching chars up by their place value; I can't find a way where the two names would ever have the same value... I am operating under the assumption that both lowercase and uppercase letters are treated identically concerning value, as this appears to be made implicit through the examples given. (so "A" == 1 and "a" == 1, meaning that a downcased name is equivalent to the mixed case, or uppercase equivalent; so "Elizabeth" == "ELIZABETH" == "EliZabETh" etc etc)

    First, the letters and their associated values: alpha_value = { "a"=>1, "b"=>2, "c"=>3, "d"=>4, "e"=>5, "f"=>6, "g"=>7, "h"=>8, "i"=>9, "j"=>10, "k"=>11, "l"=>12, "m"=>13, "n"=>14, "o"=>15, "p"=>16, "q"=>17, "r"=>18, "s"=>19, "t"=>20, "u"=>21, "v"=>22, "w"=>23, "x"=>24, "y"=>25, "z"=>26}

    Elizabeth split into chars (downcased for ease) and valued out by char

    [["e", 5], ["l", 12], ["i", 9], ["z", 26], ["a", 1], ["b", 2], ["e", 5], ["t", 20], ["h", 8]]

    sum of letters:

    5 + 12 + 9 + 26 + 1 + 2 + 5 + 20 + 8 == 88 # true

    Matthew split into chars (downcased for ease) and valued out by char

    [["m", 13], ["a", 1], ["t", 20], ["t", 20], ["h", 8], ["e", 5], ["w", 23]]

    sum of letters:

    13 + 1 + 20 + 20 + 8 + 5 + 23 == 90 #true

    Given the names and weights for the test case

    "Elijah,Chloe,Elizabeth,Matthew,Natalie,Jayden" [1, 3, 5, 5, 3, 6]

    I would reason this out to be:

    names_array = ["Elijah", "Chloe", "Elizabeth", "Matthew", "Natalie", "Jayden"] weights = [1, 3, 5, 5, 3, 6]

    Which would mean that the respective "weights" of each name in question is 5

    So based on the weights, and the totals of the characters, they come out to

    different values...

    elizabeth = 88 * 5 ==> 440

    matthew = 90 * 5 ==> 450

    Based on this step by step, I can't see where I might be going wrong with the calculation. They have different total values based on the characters in the names and the assigned weights. Why would "Elizabeth" not be ordered after "Matthew" in this context?

    Could anybody help me, please?

    My code works correctly with all basic tests except two: ("Aubrey,Olivai,Abigail,Chloe,Andrew,Elizabeth", [3, 1, 4, 4, 3, 2], 4) Expected: 'Abigail', instead got: 'Chloe' and ("Elijah,Chloe,Elizabeth,Matthew,Natalie,Jayden", [1, 3, 5, 5, 3, 6], 2) Expected: 'Matthew', instead got: 'Elizabeth'.

    Both of them I counted manually and got the same result as my code. What is wrong?

    Ok, I can't understand this. My code (python) works in every single instance except for where the code is telling me it's supposed to be returning Matthew instead of Elizabeth. The system isn't reporting the test parameters to me, so my only assumption is that both numbers have the same weight, otherwise this wouldn't be an issue.

    Elizabeth has a total value of 97, Matthew has a total value of 97, if they're the top contenders and they're tied then Elizabeth needs to be returned, but the test keeps saying Matthew is the correct answer, and that's can't be right. This is the only test that's failing, can someone please help me understand what I'm missing here without referring me to the comments below? I've read them all, the solution isn't there.

  • wiz0rd Avatar

    I'm trying to solve this with python and I am getting the following: STDERR Traceback (most recent call last): File "main.py", line 85, in randomTests() File "main.py", line 83, in randomTests Test.assert_equals(rank(st, we, k), rankSol(st, we, k)) File "main.py", line 52, in rankSol res.append([f[i], we[i] * scoreSol(f[i])]) IndexError: list index out of range

    I know list index out of range is usually from calling an out of range index value on a list, like lista = [0, 1, 2] and then I try and run lista[3] but I am not really sure where this could be happening in my code. Any thoughts are appreciated!

    Thanks!

    Is there a way to flag a Kata? Because during the attempt phase the input is not shown. Therefore, it is extremely difficoult to find where the code goes wrong.

  • The_Boss_007 Avatar

    It is unfortunate, that the test results do not show the input. Therefore, it is very difficult to figure out where the code goes wrong.

  • MarkyMark1000 Avatar

    From the question:

    1. "An array of random weights is linked to the firstnames and each som is multiplied by its corresponding weight to get what they call a winning number."

    2. The Example: PauL -> som = length of firstname + 16 + 1 + 21 + 12 = 4 + 50 -> 54 The weight associated with PauL is 2 so PauL's winning number is 54

    Given that part 1 states that "each som is multiplied by its corresponding weight", this doesn't make sense. Surely PauL's winning number should be 108, not 54.

  • BatonSzachista Avatar

    My code in C keeps passing most of the tests but fails one, returning "Test Crashed, Signal Code:11". I know it stands for segmentaion fault but this doesn't really seem right.

  • Chrono79 Avatar

    Rename the partial value of the instructions to something else, n is already used as a function's argument and that's a little confusing.

    The length of the firstname is added to the sum of these ranks hence a number m. An array of random weights is linked to the firstnames and each m is multiplied by its corresponding weight to get what they call a winning number.

    Something like that or whatever name not used in another part you want would be fine.

  • johnnybar Avatar

    Hi, I'm definitely missing something, so could someone please clarify? - If n is calculated by the first name length + rank of each letter in the name, why is n provided as an argument in the function? I would think we would get the string argument, weights argument and then calculate n ourselves, using it to calculate the 'winning number'... Thanks for your help

  • Constructer Avatar

    Why I'm see different result of sorting array in Chrome and site (Codewars) on some random tests? Visual Studio Code give result like codewars and I'm not understand it. Code in clear Chrome work perfect.

  • Sepero Avatar

    It's a good challenge, but the obscurity in the description takes away from it's value. The description on this kata could make a few things a little more explicit:

    1. Parameter n starts from 1 (not 0).
    2. The higher rank = lower n (the largest number rank will be n=1).
    3. Case does Not matter when calcutaing ranks, so you should probably convert names to all lower or upper case before calculating ranks.
    4. You will need to be able to fully sort the names alphabetically, ex. Brain comes before Brian.

    . The best kata's are the one's which present clear rules for answering the challenge, and the challenge is implementing those rules into code.

    I'm not clear on the instructions and the purpose of calculating the winning number for each person, do we have to sort each winning number-person pair, and then return the name whose index= n? If someone can paraphrase the whole instruction more clearly, I'd really appreciate it

  • jsdevtom Avatar

    Thank you for this. I recommend naming the variables explicitly next time. For example naming n what ever that was (index_of_winner?) and we (weights?). Such short names are advised against in books such as clean code because it unnecessarily obfuscates the codes meaning

  • pierovera Avatar

    Upon returning to this kata, I've found out why it acts strangely in C. Sometimes, during random testing, there will be a comma at the end of the list of participants, which, if you're counting participants using the delimiting character, will make the program crash. I think it is pretty ridiculous to have to account for this, when the kata does not specify anything regarding empty elements in the list. Additionally, since the sample tests do not have any cases like this one, it makes it kind of cryptic to decipher the issue. It would be nice if this could be revised. Thanks.

    Hi, first of all, congrats for the kata, it's nice!. I've written my code and it passes most of the test (but not all). Focus on basic test, my code passes 16 of 18 tests. I've been reviewing my code for long time but I don't find the error, I need help. I write in console lots of logs in order to help me, and this is the result:

    Data entry: st = Elijah,Chloe,Elizabeth,Matthew,Natalie,Jayden we = 1,3,5,5,3,6 n (position searched) = 2 letter E weigths 5 letter L weigths 12 letter I weigths 9 letter J weigths 10 letter A weigths 1 letter H weigths 8 length of Elijah = 45 weigth of Elijah = 1 winning number of Elijah = 45 letter C weigths 3 letter H weigths 8 letter L weigths 12 letter O weigths 15 letter E weigths 5 length of Chloe = 43 weigth of Chloe = 3 winning number of Chloe = 129 letter E weigths 5 letter L weigths 12 letter I weigths 9 letter Z weigths 26 letter A weigths 1 letter B weigths 2 letter E weigths 5 letter T weigths 20 letter H weigths 8 length of Elizabeth = 88 weigth of Elizabeth = 5 winning number of Elizabeth = 440 letter M weigths 13 letter A weigths 1 letter T weigths 20 letter T weigths 20 letter H weigths 8 letter E weigths 5 letter W weigths 23 length of Matthew = 90 weigth of Matthew = 5 winning number of Matthew = 450 letter N weigths 14 letter A weigths 1 letter T weigths 20 letter A weigths 1 letter L weigths 12 letter I weigths 9 letter E weigths 5 length of Natalie = 62 weigth of Natalie = 3 winning number of Natalie = 186 letter J weigths 10 letter A weigths 1 letter Y weigths 25 letter D weigths 4 letter E weigths 5 letter N weigths 14 length of Jayden = 59 weigth of Jayden = 6 winning number of Jayden = 354 [ { name: 'Matthew', weigh: 450 }, { name: 'Elizabeth', weigh: 440 }, { name: 'Jayden', weigh: 354 }, { name: 'Natalie', weigh: 186 }, { name: 'Chloe', weigh: 129 }, { name: 'Elijah', weigh: 45 } ] Expected: 'Matthew', instead got: 'Elizabeth'

    ================================================================ I hope someone can help me because I follow the figures until the last array (sorted) and I don't understand why "Matthew" is expected in position 2 in this test. I assume the kata is correct and I'm wrong, so I'll be grateful if someone can help me. Thanks in advance.

    5. Benjamin - 76 <- It is the "correct" answer

  • pierovera Avatar

    I am unable to complete this kata in C. My program runs all the sample tests, as well as any tests I run myself outside of this. However, during random testing, it gets through (on average) 30 tests before one just segfaults the program and fails. It gives me absolutely no way to fix the issue, as I cannot reproduce it locally and it doesn't tell me what input it tried using that crashed the program. It doesn't seem to follow any pattern, it just will sometimes get tripped up and crash. I cannot complete the kata.

    Read the instructions really carefully, there's a lot going on. The bit about adding the length of the array to the name's score before multiplying by the weight is easy to miss.

  • arkada38 Avatar

    The length of the firstname is added to the sum of these ranks hence a number n.

    PAUL -> n = length of firstname + 16 + 1 + 21 + 12 = 4 + 50 -> 54
    length of firstname = 4 not 3

    And random tests will fail (e.g. C#).
    Because ranks are numbered from 0 in tests solution.
    This contradicts to the condition.

    The frustration is real. For the first time, I struggled to understand a kata description.

    Would appreciate any help. My logic:

    • Calculate the sum of letters per name
    • Add the length of the name to that sum
    • Multiply the sum by corresponding weight (we) - get the winning number
    • ???

    At what point should I engage the 3rd argument n ?

    it was a difficult description for me. It would be nice, if you add result array

  • marco.valloni Avatar

    I think that also in PHP there're some issue regarding the sort order of the cases with more than 1 result,

    In one case I obtain "Elizabeth" and "Matthew" and the right one was "Matthew" (So inverse alphabetical order) but in another test with "Abigail" and "Chloe" the right one was "Abigail" (So alphabetical order).

    Can be that there's some mess in the test at this point, with the reverse order I'll pass also all the standard test under the exercise but during the submit there's no way I can find the right sorting.

    I wish the problem statement would be more detailed in describing how the winner is chosen if there are equal ranks. Without checking the discussion thread and test cases, I would not figured out what was wrong in my understanding of the problem.

    In general, the kata is fine and requires you to understand what is the best way to represent the participant records.

    This testcase is wrong!?

    st: Addison,Jayden,Sofia,Michael,Andrew,Lily,Benjamin / we: 4, 2, 1, 4, 3, 1, 2 / nth: 4 Expected: Benjamin Error. Expected Benjamin but got Addison

    Wish this kata had better examples and explanation.

    Hello, I'm not realy good in English, so can u help me to understand, what is the "n" in input data ("name, name,.. ,name", [weight, weight,.., weight], that n). what should i do with this array: [Addison] => 292 [Jayden] => 130 [Sofia] => 55 [Michael] => 232 [Andrew] => 213 [Lily] => 62 [Benjamin] => 152

    Is it the position in rightly sorted array?

    Hey I tried to make this kata but when the solution is evaluated with randoms say me that the name is wrong, i checked manually and the solution is correctly

    Example:

    Testing Rank: William,Aubrey,Michael, [3,1,6], 2

    Solution:

    [ 348, 258, 78 ] [ 'Michael', 'William', 'Aubrey' ]

    Result:

    ✘ It should work for random tests too - Expected: 'Aubrey', instead got: 'William'

    Note: The problem is only with randoms

  • refede Avatar

    (Python) Hi, I´d like to know, what is the test for this result: ✘ 'Chloe' should equal 'Abigail'

  • johnhalsey Avatar

    Ive completed this Kata but I can't see other peoples solutions. It says I have not completed it!

  • iCombii Avatar

    I'm not sure what his point is with receiving n. The other things with receivng and working with the string and array I understand.

  • docgunthrop Avatar

    I'm hoping to get some clarity as I appear to be having issues producing the correct output when there is more than one name with the same winning number.

    In the description, you state: "When two people have the same winning number sort them alphabetically by their firstnames."

    To clear up any confusion, I modified my code so that the output returns the first name that starts with a letter with a lower rank ("A" = rank 1, "B" = rank 2, etc.), basically in alphabetical order. When that didn't work, I changed it to return the name with a leading character that ranks higher, but I got errors there as well.

    As a last resort, I'm posting this comment to see if I can get some clarification on "alphabetical order".

    Yo I think one of the test case is wrong (Ruby) Below are the results I got after submit (run tests step was ok) Shouldn't it be rank 2 Elizabeth? How the hell it is expected to be Matthew? I printed both n and the array values out to check. 4 [["Addison", 264], ["Michael", 204], ["Andrew", 195], ["Benjamin", 136], ["Jayden", 118], ["Lily", 58], ["Sofia", 50]] ✔ Test Passed: Value == "Benjamin" 2 [["Matthew", 450], ["Elizabeth", 440], ["Jayden", 354], ["Natalie", 186], ["Chloe", 129], ["Elijah", 45]] ✘ Expected: "Matthew", instead got: "Elizabeth"

  • htbkoo Avatar

    When I tried to submit my code, the fixed tests failed with an strange message "✘ 5". Does not seem like I break the test since nothing like "Expected: <>, Actual: <>" was printed. Would be great if any hints could be given.

    Really good kata! Thanx!

  • bladez Avatar

    I would really like to get this kata solved but it's impossible without getting any help on my question regarding C# test case. I'd truly appreciate if someone could help with this. I can post my solution here if someone tells me how to do it so that the code formats correctly here.

    Like I said my problem is with this test: test1 Expected string length 6 but was 40. Strings differ at index 0. Expected: "Sophia" But was: "Names and weights array lengths not even" -----------^ at RankTests.test1 () <0x416e9610 + 0x00717> in :0

    I made some console logging and in that specific test case st parameter has five names (Sophia,Robert,Abigail,Grace,Lagon) but we parameter has six items. One of my checks verifies that both must have equal amount of items (if they don't "Names and weights array lengths not even" string is returned). Does the st parameter miss one name or does the we parameter have one weight too much?

  • bladez Avatar

    Hi! I was able to do the sample test run successfully but got this one on submit:

    test1 Expected string length 6 but was 35. Strings differ at index 0. Expected: "Sophia" But was: "Names and weights array lengths not even" -----------^ at RankTests.test1 () [0x00000] in :0

    That seems to have been triggered on my check for names array length and we array length (both should have equal length). I thought for each name there must be an entry in we array. Am I wrong?

    When runnning test all passes well, but when submitting solution "unknown error" occures on C#

  • user7261034 Avatar

    Seems I'm doing something wrong. Details specify: "When two people have the same winning number sort them alphabetically by their firstnames." But when I do this a test fails (because it expects reversed order). I change the code accordingly and the test passes. But then another test fails because it expects alphabetical order.

    Python: 'William' should equal 'Willaim' Typo?

    This might be an interesting test case to add.

    Test.assert_equals(rank("A,B,C,A", [1, 1, 1, 10], 1), "A")
  • SpeakerLocke Avatar

    That looks kinda bullshit, when your program runs through all available test without issues, and even runs through test you wrote yourself, but crashes on the hidden ones. After 30 mins you start thinking that hiddens are fucked up.
