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”. Examples: WebOne of the ways is to traverse the matrix diagonally in a direction until it can not go any further. At that point, change the direction to move one step right or one step down according to the current position of traversal. The code executes in the following sequence. Move one step to the Right. If you can not move Right, move one step Down. imdb apocalypse now cast
