Difficulty:
(157)
Rate
Given a square matrix A of size n x n, write a function to compute the sum of the elements on both the main diagonal and the anti-diagonal of the matrix.
  • Main diagonal: The diagonal running from the top left to the bottom right.
  • Anti-diagonal: The diagonal running from the top right to the bottom left.
If the matrix has an odd size, the center element (which lies on both diagonals) should only be counted once.
