Write it, run it, read the output

This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.

TASK

Store the running 5 x 5 matrix and use matrix[i][i] for the left diagonal and matrix[i][n - 1 - i] for the right diagonal. Print both diagonals on separate lines, including 13 in both lines.
