Binary Tree Zigzag Level Order Traversal

Explore how to implement zigzag level order traversal for binary trees by alternating left-to-right and right-to-left node visits each level. Understand the problem constraints, practice problem interpretation, and develop the code solution through a hands-on approach within the breadth-first search context.

We'll cover the following...

Statement

Given a binary tree, return its zigzag level order traversal. The zigzag level order traversal corresponds to traversing nodes from left to right for one level, and then right to left for the next level, and so on, reversing direction after every level.

Constraints:

  • The number of nodes in the tree is in the range 00 ...
