Question

what is the best way to check the matrix, is it a "magic square"?
A magic square is a square table filled with different numbers in such a way that the sum of the numbers in each row, each column and on both diagonals is the same 🌌

What is the best place to start? Check diagonals first? and then the lines? or how? And is it worth using boolean variables to solve this problem?
