Retired as a duplicate. See https://github.com/codewars/content-issues/issues/57.
This kata is a subject to a deduplication process here: https://github.com/codewars/content-issues/issues/57 . Please join the discussion and share your opinion so duplicate kata could be identified, and then retired.
Kata retired.
Ruby: Testing: 0x^27; Expecting: 0x^26 Testing: 139x^0; Expecting: 0x^-1
thats tests seems wrong, they inconsistent with description, sample tests and common sense
Ruby:
Testing: -191x^1; Expecting: -191x^0. Input with^1, output with^0?..Ruby 3.0 should be enabled, see this to learn how to do it
Kata retired.
Is this really a 7 kyu kata ?!
Not 7 kyu at all. At least 6 kyu. Ridiculous.
Ruby translation kumited -- please check and approve (note: author is deleted)
APPROVED :)
Can you please break down each example into one pair per line? It's literally unreadable as of now.
(You can force a line break by inserting two whitespaces at the end of the line. Double line break denotes a paragraph break.)
huh, so that's how that works
Note that the initial code still has its argument named
str.thanks, fixed
there's really a problem with the new rules for approval. Only 3 completions and this one is already approvable.
I raise this issue to give time to the author to change the description and/or the tests so that the kata does not go out of beta before it could have a "stable form".
Added examples to description and test cases to cover edge cases.
Looks like a duplicate: https://www.codewars.com/kata/derivatives-of-type-x-n And probably derivate #2 exists too (https://www.codewars.com/kata/derivative);-)
Looks like the derivatives-of-type-x-n has been backlogged with unresolved issues for a year. I doubt it's ever coming out of beta.
There's one little open issue;-)... It's easy to edit/correct it, haven't looked at it only remembered that i solved a similar one long ago;-) I think it's not a reason to create a same kata (the other one is solvable too)
But... i mark the issue as resolved (maybe tomorrow i will correct the older one)... So keep in mind: first search, second publish:-)...
@Smile67 or ZED.CWT: please stop downranking katas. This one is never 8kyu even if you solve it in less than 2 minutes
My ranking was 7kyu and i think it's not more;-)... By the way i think it's a duplicate
You're right, there is a similar one, with some minor differences (it looks at a polynomial). I didn't notice until you mentioned.

hi,
"3x"doesn't fit with the description. it should be"3x^1". Or you must change the descriptionstr(this is a type in python) =>sor something else.EDIT: If you want to test for edtge cases, you could test these:
ax^0(or justaif you modify the description) =>0ax^1(or justaxif you modify the description) =>a0x^b=> 0 (but is that useful...?)I really do need help with my math homework, thanks!
update of the message just above (it seems you posted just before my "edit")
