Problem with c# test case 5.
I add console output for input params and get next:
Test output:

Test5
Expected: True
But was: False
at AreTheySameTests.Test5 () [0x00000] in :0

Input params:
A length: 9
a=[121, 144, 19, 161, 19, 144, 19, 11, 1008]
B length: 8
b=[121, 14641, 20736, 36100, 25921, 361, 20736, 361]

Inline execution log:
Not found b in a: 36100
36100 = 190 * 190, and array a don't contain 190.
Test 5 like part of description (only to array a added 1008):
" a = [121, 144, 19, 161, 19, 144, 19, 11]
b = [121, 14641, 20736, 36100, 25921, 361, 20736, 361]
comp(a,b) returns false because in b 36100 is not the square of any number of a."

Add please {50, 25} to test cases.
This solution pass all test cases (and previus subversion), but have error (don't count order).

I just did not read the full condition before sent the final result. When I saw that moment, I made a second version of the solution.
It is necessary to add to this kata test incorrect sequence.
Sorry for bad english.
