Checking whether two binary trees are identical Getting the inorder traversal for a given binary tree Getting the postorder traversal for a given binary tree Getting the preorder traversal for a given ...

# Given a binary tree, return the zigzag level order traversal of its nodes' values. (ie, from left to right, then right to left for the next level and alternate between).

Height of the tree: A tree’s maximum number of level is denoted as tree height (or ... we can output the nodes which have searched before in order. 4. Another Algorithm of Binary Tree Traversal ...
