I am so dumb... figured it out. :)

Well I see no internal logging after that point, so I have no idea what that might be. :)

Cheers and thanks for the time.

Are you sure? The last thing I am logging as input, before the Expected:true is:

2,2,3
4,9,9
Sorted:
2,2,3
4,9,9

9 not square of 2

After the Expected: true I have no logs from my program.

I seem to have the opposite problem with the multiplicity test cases:

a = {2,2,3};
b = {4,9,9};

Expected: true
Actual: 0

Why is this expected true?
