Write a Modular C Programming code to solve 2D ARRAYS- Rinku’s Sudoku square | to identify whether the square is Rinku’s Sudoku square.
Rinku was reading a newspaper one-day morning. She came across a Sudoku game where she tried to solve it in a different way. For a N x N Sudoku game, she adds up all the column-wise numbers. If all the column-wise sums are equal, then she called it Rinku’s Sudoku square.
Apply a problem-solving framework and write a modular C program to identify whether the square is Rinku’s Sudoku square.
Input Format
N – indicates the Size of the Sudoku square.
Constraints
Rows and columns should be equal.
Output Format
Display a message whether Sudoku square is Rinku’s Sudoku square.
