Solution: Binary Tree Zigzag Level Order Traversal
Explore how to perform zigzag level order traversal on a binary tree by alternating traversal directions each level. Understand the use of a deque to efficiently manage node processing for left-to-right and right-to-left orders, with clear steps and time-space complexity analysis.

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, right to left for the next level, and so on, reversing the direction after every level.
Constraints:
-
The number of nodes in the tree is in the range to ...
