WebApr 6, 2024 · Method 2 uses the following rules to get the sum directly. 1) If the node is a leaf node then the sum of the subtree rooted with this node is equal to the value of this node. 2) If the node is not a leaf node then the sum of the subtree rooted with this node is twice the value of this node (Assuming that the tree rooted with this node is SumTree). 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:

Vertical Zig-Zag traversal of a tree is defined as: Print the elements of the first level in the order from right to left, if there are no elements left then skip to the next level. Print the elements of the last level in the order from left ...
WebAug 22, 2024 · Also when we will traverse the level from bottom we will mark flag as 0 so that next time we traverse the tree from left to right and then decrement the value of j so that next time we visit the level just above the current level. Repeat the whole process until the binary tree is completely traversed. Below is the implementation of the above ... WebGiven a Binary Tree, find its Boundary Traversal. The traversal should be in the following order: Left boundary nodes: defined as the path from the root to the left-most node ie- the leaf node you could reach when you …
