There is still unfixed issue in C# tests.
Description says "There will always be ONLY ONE integer that appears an odd number of times."
But in that test array {20,1,-1,2,-2,3,3,5,5,1,2,4,20,4,-1,-2,5,1,1,2,-2,5,2,4,4,-1,-2,5,20,1,1,2,2,3,3,5,5,4,20,4,5,10} we have '-1' that appears 3 times and '10' that appear 1 time.
Those are the input values of several tests together.
There is no such test in C#, at least now.

@Syyno ~ Not sure how you arrived at that, because your code would crash if the length of the signature was less than 3.
I just solved it and it's always 3 numbers. Please fix your code =/
Sorry, forgot to mention - c#
what language?
Description says "Signature will always contain 3 numbers". But some tests has 1 or 2 values. Please, fix description/tests.
