Shatha once solved a problem that required calculating the sum of the two diagonals of a square matrix (Diagonal sums question). She considered that problem medium-level. Now, she wants to challenge you with something a bit harder to test your problem-solving skills.

So lets go:

You are given a square matrix of size n x n where n is an odd number. Your task is to:

• Calculate the sum of:

  • The main diagonal (top-left to bottom-right)

  • The secondary diagonal (top-right to bottom-left)

  • The middle row

  • The middle column

Then check whether all four sums are equal.
