All Posts. Approach: d) When row and column are equal then add it to the sum. Program: The source code to find the sum of the right diagonal of the matrix is given below. If you use 2d array, 1st element of 1st box,2nd element of second box and third element of third box will be the set of diagonal elements. Thus the code should return 14. The given program is compiled and executed successfully. 1. Write a java program to get sum of the element of Matrix. Given the same matrix, to get what you call the right diagonal sum, you need to add these elements: m [0] [2] m [1] [1] m [2] [0] You can already identify a definite pattern of change with the above examples but if not, listing out the elements involved in calculating diagonal sums for 4x4, 5x5, etc. Module Module1 Sub Main Dim arr (,) As Integer = New Integer (3, 3) {} Dim sum As Integer = 0 Console. Traverse through given 2D list from 0 to list size and store sum of left to right diagonal value to leftDiagonal variable and right to left diagonal value to rightDiagonal variable. type arrayName [ x ] [ y ]; Where type can be any valid C data type and arrayName will be a valid C identifier. More About Main Diagonal : The sum of the elements of the main diagonal of a matrix is called Trace of the matrix. The solution in this case would be 9. We have to calculate the sum of all the elements present at its diagonals i.e. Answer (1 of 2): You can use a 1d array or a 2d areay, both will work as its a 3×3 matrix, 1st,5th,9th element in1d array are digonal elements.
