Diagonal traversal of tree gfg
WebIn the above tree, the diagonal distance is represented by using the notation 'd'. There are two rules for marking the diagonal distance: The 'd' variable increments by 1 only when the node has a left child. For every right child, 'd' remains same as of parent ('d' remains the same for right child). 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:
