Solution: Binary Tree Zigzag Level Order Traversal
Understand how to perform a zigzag level order traversal of a binary tree by using a deque to alternate processing nodes from left to right and right to left at each level. Learn to manage traversal direction, implement the algorithm efficiently, and analyze its time and space complexity.

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 ...
