WebIn Matrix Diagonal Sum problem a square matrix of integers is given. We have to calculate the sum of all the elements present at its diagonals i.e. elements at primary diagonal as well as secondary diagonal. Each element should be counted only once.

WebJan 29, 2024 · The secondary diagonal is. 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. fi載點WebAug 1, 2024 · Time Complexity: O(N 2), where N represents the number of rows and columns of the given matrix. Auxiliary Space: O(1), no extra space is required, so it is a constant. Scalar matrix.
