Trick for finding preorder , postorder and inorder of a tree : For Pre - order - Traverse the tree from top to bootom and left to right, when you visit the node first time print it.
For Inorder - Whenever you vist the node second time , print it.
For Post Order : When you visit the node 3rd times print it.

Given a binary tree, determine if it is height-balanced. For this problem, a height-balanced binary tree is defined as: a binary tree in which the depth of the two subtrees of every node never differ by more than 1.

Assume you are given “preorder” and “inorder” traversal result of a Binary Tree. Write an algorithm (pseudocode) that constructs the Binary Tree. For example, you can start with the Pre-Order and In-Order traversal of the same tree given below. Pre-Order = 80, 50, 10, 70, 100 In-Order = 10, 50, 70, 80, 100
