Binary Tree Zigzag Level Order Traversal

Try to solve the Binary Tree Zigzag Level Order Traversal problem.

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, and then right to left for the next level, and so on, reversing direction after every level.

Constraints:

  • The number of nodes in the tree is in the range 00 to 500500.

  • −100≤-100 \leq node.data ≤100\leq 100
