WebMar 18, 2024 · This approach defines a function called “print_diagonals_2” that takes in a matrix as an argument. It then initializes two empty lists to store the elements of the matrix’s diagonals. Using a loop, it iterates through the matrix and appends the elements of the two diagonals to their respective lists. Finally, it prints the two diagonals. Algorithm 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:
