Binary Tree Zigzag or Spiral Level Order Traversal | Tree Data Structure playlist C++ | Hello World

This is the video under the series of DATA STRUCTURE & ALGORITHM in a TREE Playlist. We are going to understand How to find the Zigzag Level Order Traversal of a Binary Tree or Level order traversal in spiral form. We understand How to use Queue data structure for Finding Level Order Traversal. Join My Telegram channel for more Updates: https://telegram.me/helloworldbyprince ► 103. Binary Tree Zigzag Level Order Traversal Given the root of a binary tree, return the zigzag level order traversal of its nodes' values. (i.e., from left to right, then right to left for the next level and alternate between). Input: root = [3,9,20,null,null,15,7] Output: [[3],[20,9],[15,7]] or Input: 10 / \ 20 30 / \ 40 60 Output: 10 20 30 60 40 We also Provide courses on Competitive Programming and Data structure and Algorithms.
