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”..

Tree Traversals (Inorder, Preorder and Postorder)
WebSep 16, 2024 · Given a binary tree and a key, insert the key into the binary tree at the first position available in level order. Recommended: Please try your approach on {IDE} first, before moving on to the solution. The idea is to do an iterative level order traversal of the given tree using queue. If we find a node whose left child is empty, we make a new ... WebYour task is to complete the function zigZagTraversal () which takes the root node of the Binary Tree as its input and returns a list containing the node values as they appear in the Zig-Zag Level-Order Traversal of the Tree.

Check if a given Binary Tree is SumTree - GeeksforGeeks
WebExample 1: Input: 3 / \ 1 2 Output: 1 Explanation: The sum of left subtree and right subtree is 1 + 2 = 3, which is the value of the root node. Therefore,the given binary tree is a sum tree. Example 2: Input: 10 / \ 20 30 / \ 10 10 Output: 0 Explanation: The given tree is not a sum tree. For the root node, sum of elements in left subtree is 40 ... WebApr 9, 2024 · Approach: For Principal Diagonal elements: Run a for a loop until n, where n is the number of columns, and print array [i] [i] where i is the index variable. For Secondary Diagonal elements: Run a for a loop until n, where n is the number of columns and print array [i] [k] where i is the index variable and k = array_length – 1.
