Sum across the secondary diagonal: 4 + 5 + 10 = 19. Difference: 4 - 19 = 15. Now the last step is to find the difference between the sum of diagonals, so add the first diagonal and the second diagonal after that mod the difference so 4 - 19 = 15. Hence we got our solution. Note: x is the absolute value of x.

WebMay 31, 2024 · Along the first diagonal of the matrix, row index = column index i.e mat[i][j] lies on the first diagonal if i = j. Along the other diagonal, row index = n – 1 – column index i.e mat[i][j] lies on the second diagonal if i = n-1-j.
