Same issue!

12 seconds... Even if go for the most naive solution it should work.

How come, that it's not?

Hi, there!
having this error:
tests/Fixture.cs(23,32): error CS7036: There is no argument given that corresponds to the required formal parameter 'sudoku' of 'Sudoku.IsValid(int[][])'

in C# the initial code looks like this:

class Sudoku
{
public Sudoku(int[][] sudokuData)
{
//Constructor here
}

public bool IsValid()
{
throw new NotImplementedException();
}
}

I had implemented IsValid() function but what I need to do in constructor????
pass a sudokuData to IsValid? any ideas?

If it passed all tests - why their is an error? If my code do not return nothing how it passes tests?

STDERR
Traceback (most recent call last):
File "main.py", line 14, in
Test.describe("First 5 numbers", test_range(5) )
File "main.py", line 9, in test_range
test.assert_equals( len(result), n, 'Incorrect length for n = {}'.format(n))
TypeError: object of type 'NoneType' has no len()

What does that mean?

Oh, now I see.. Thank You

Excuse me, but how they see what is the test-case, and what is the expected answer?

I see only "Test passed" or "Failed" and if failed I see 'NO' should equal 'YES'.... Thank You
