    Nice kata! Thanks myjinxin2015

    Kata unsolvable, impossible test assigned - [-3, 4, 5, 2, 0, -10] --> [(-3 + 4), (5 + 2), (0 + -10)] --> [1, 7, -10]

    Given as we're meant to sum intervals of prime or non-prime numbers, this test is wrong. This test claims that -3 and 4 are an interval of a prime or non-prime numbers. -3 is prime while 4 isn't - meaning they shouldn't be sum'd.

    Either this question is impossible or I read the instructions wrong. Would appreciate a reply to help affirm my claim or corret me if I am wrong.

      That depends on your definition of prime numbers, if they're numbers greater than 1, then -3, isn't one.

      Ya'know, this was a google search away but I still let my pride win and be so sure of what a prime number is. Gonna delete this to undo the shame. If there is any hope for me. Thanks Chrono79.

    Earlier wthit56 raised a valid question about the description of the ending condition. I see that question was closed, but this is still confusing. The description reads as if you would have to keep repeating the process until the original input array is obtained. But that's not true. I think if this confusion were resolved, maybe more people would try this kata. I would suggest an edit like this: "Repeat the process until there are no intervals of prime or non-prime numbers with a length greater than one." When I assumed this to be the ending condition, I was able to solve the kata.

      Added two testcase:

      Test.assertDeepEquals(simplifiedArray([-3,4,5,2,0,3]),[1,7,0,3])
Test.assertDeepEquals(simplifiedArray([-3,4,5,2,0,0,0,3]),[1,7,0,3])

      Thank you for your advice ;-)

    In the description: if the resulting array is different from the initial one, repeat the process; otherwise return the resulting array. So you keep applying the algorithm until you get the original array you got in the first place? Sounds like you could just return that original array and skip the algorithm altogether! @.@"
