@Deantwo Thanks for the explanation. almost smashed my pc in rage

Your code returned "6 -214", but the test was expecting "542-214".

It is a very common mistake people make in this kata. You now have to learn the difference between sorting a list of strings and sorting a list of numbers. Have fun!

Here is a full comparison as an example:

 Int   String
 542   6       MAX
  54   542
  29   54
   6   5
   5   4
   4   4
   4   29
   1   1
   0   0
  -3   -64
  -6   -6
 -64   -3
-214   -214    MIN

Which language are you referring to? Probably because your code is returning "6 -214".
