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. By using two loops we traverse the entire matrix and calculate the sum across the diagonals of the matrix. 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. Example mat = [[1,2,3], [4,5,6], [7,8,9]] 25. Explanation: chinese buffet in troy
C++ Program to Maximize sum of diagonal of a matrix by rotating …
WebMar 21, 2024 · A two-dimensional array or 2D array in C is the simplest form of the multidimensional array. We can visualize a two-dimensional array as an array of one-dimensional arrays arranged one over another forming a table with ‘x’ rows and ‘y’ columns where the row number ranges from 0 to (x-1) and the column number ranges from 0 to (y … 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. WebApr 9, 2024 · Approach: For Principal Diagonal elements: Run a for a loop until n, where n is the number of columns, and print array [i] [i] where i is the index variable. For Secondary Diagonal elements: Run a for a loop until n, where n is the number of columns and print array [i] [k] where i is the index variable and k = array_length – 1. chinese buffet in toms river
