Homework 3.8 Sudoku: An Edge case

0

I have found the following Edge case:

list_ch = [[1,2,3],
           [2,1,3],
           [3,1,2]]

Should it return False, in the same way this one does?:

incorrect = [[1,2,3,4],
             [2,3,1,3],
             [3,1,2,3],
             [4,4,4,4]]

Thanks!

I don't see how that's an edge case. Yes, it should return False; the second and third columns are invalid.

Yup, Edge case is too much "yellowish".
But I hope it helps people to not just go working via Rows but also via Columns. Or they will score a Failed ;)
I have to rework my code after finding this specific case. My code wasn't able to discover this is a false Sudoku at all.

@vicmarcal What does "yellowish" mean in this context?

That will definitely return false because it does not meet the requirements of a standard Sudoku! You cannot have the same values in the same column, like 3, 3 1 etc. good luck

You must not only check the rows and columns, but according to exercise statement you must also check that numbers are 1 to 3 for the first grid, or 1 to 4 for the second

I won't give more hints at this point ;-)
