Solution: Binary Tree Zigzag Level Order Traversal
Explore the zigzag level order traversal of a binary tree using breadth-first search. Understand how to alternate between left-to-right and right-to-left traversal by using a deque. This lesson teaches you to manage traversal direction and process nodes efficiently at each level to produce the correct zigzag order.

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 ...
