By Sree Lekshmi P

The popular Sudoku game made in C++ format. It is in 9x9 grid and uses backtracking that try different solutions until finding a solution that “works".

The source code is for the popular Sudoku game, where we arrange numbers from 1-9 such that they appear only once in a row and column of a 9x9 grid.

The backtracking method is used in this code. The initial values are hardcoded, but we can also get the same input from the user. Backtracking is used when we need to find rows and columns that are not assigned any values. The purpose is to fill boxes in every square with no. ranging from 1 to 9.
