Challenge overview
Hello and welcome to the challenge!
Sudoku is a type of puzzle in which certain numbers must be arranged within a 9x9 grid. The aim is to avoid repeating any number in the same row or column.
Your goal in this assignment is to write a program to check if the given Sudoku solution is correct. Every cell of the grid can contain an integer between 0 and 9. Zero represents an empty cell and if the board contains one or more empty cells, it is considered to be an invalid solution.
Have fun and good luck! :)
