Solution: Binary Tree Zigzag Level Order Traversal
Explore how to implement zigzag level order traversal of a binary tree using a breadth-first search approach with a deque. Learn to alternate between left-to-right and right-to-left traversal at each level and understand the algorithm's time and space complexity. This lesson guides you through managing traversal direction and processing nodes efficiently in tree data structures.

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 ...
