thanks!

already stated in description, so it's clear enough

so me ;)

Okay, thanks. I'll keep that in mind next time. I didn't think Irevealed

hi, think about the spoiler flag, plz (comments under solutions are visible from the dashboard)

Assumptions:
0^0 = 1
0^1 = 0

here is the data in the C# test suite:

  new object[]
  {
    false,
    new int[][]
    {
      new int[] {1, 2, 6, 3, 4, 7, 5, 9, 8}, 
      new int[] {7, 3, 5, 8, 1, 9, 6, 4, 2}, 
      new int[] {1, 9, 4, 2, 6, 5, 8, 7, 3}, 
      new int[] {3, 1, 7, 5, 8, 4, 2, 6, 9}, 
      new int[] {6, 5, 9, 1, 7, 2, 4, 3, 8}, 
      new int[] {4, 8, 2, 9, 3, 6, 7, 1, 5}, 
      new int[] {9, 4, 8, 7, 5, 1, 3, 2, 6}, 
      new int[] {5, 6, 1, 4, 2, 3, 9, 8, 7}, 
      new int[] {2, 7, 3, 6, 9, 8, 1, 5, 4}, 
    },
  },

This will definitely expect false and not true. So I don't know what you did, but you did it wrong for sure. And note that when I return false directly in C#, that test is passing perfectly fine.

Regarding Sniper16's issue below.
Resolution states that the first input is not present in tests, but it is.
First column has x2 1's but expects true.

First Input IS present among the tests in C#.
Not resolved. First column has x2 1's.

Made new issue.

Why would 0^1 be equal to 1?
