Solution: Binary Tree Zigzag Level Order Traversal
Explore how to perform a zigzag level order traversal on a binary tree by applying breadth-first search with a deque. Understand how alternating traversal directions at each level allows efficient node ordering and practice implementing this approach to solve binary tree problems.

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 ...
