3. Binary Tree Zigzag Level Order Traversal Given a binary tree, return thezigzag level ordertraversal of its nodes' values. (ie, from left to right, then right to left for the next level and alternate between). For example: Given binary tree[3,9,20,null,null,15,7], 3 / \ 9 20 ...
Given a binary search tree, print the elements in-order iteratively without using recursion.Note:Before you attempt this problem, you might want to try coding a pre-order traversal iterative solution first, because it is easier. On the other hand, coding a post-order iterative version is a ...

We propose an efficient parallel algorithm to number the vertices in inorder on a binary search tree by using Euler tour technique. The proposed algorithm can be implemented in O(log N) time with O(N) processors in CREW PRAM, provided that the number of nodes In the tree is N.Masahiro ...

Morris Traversal is a method based on the idea of a threaded binary tree and can be used to traverse a tree without using recursion or stack. Morris traversal involves: Step 1: Creating links to inorder successors Step 2: Printing the information using the created links (the tree is altered...
