Diagonal traversal of matrix python
WebDiagonal Traverse LeetCode Solution - Given an m x n matrix mat, return an array of all the elements of the array in a diagonal order. Diagonal Traverse LeetCode Solution - … WebDec 12, 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.

WebMar 16, 2024 · Given a matrix A[][] of size N*M and a 2D array Q[][] consisting of queries of the form {X, K}, the task for each query is to find the position of the K th occurrence of element X in the matrix when the diagonal traversal from left to right is performed. If the frequency of element X in the matrix is less than K, then print “-1”.
