The goal of Sudoku is to fill in a 9×9 grid with digits so that each column, row, and 3×3 section contain the numbers between 1 to 9.
At the beginning of the game, the 9×9 grid will have some of the squares filled in.
Your job is to use logic to fill in the missing digits and complete the grid.
Don’t forget, a move is incorrect if:
* Any row contains more than one of the same number from 1 to 9
* Any column contains more than one of the same number from 1 to 9
* Any 3×3 grid contains more than one of the same number from 1 to 9
