Construct Binary Tree From Preorder And Postorder Traversal
Try First, Check Solution later1. You should first read the question and watch the question video.2. Think of a solution approach, then try and submit the question on editor tab.3. We strongly advise you to watch the solution video for prescribed approach.
1. You are given a partially written function to solve(Refer question video).Input Format
2. you will be given two arrays representing a valid PostOrder & PostOrder of a Binary Tree. Program is required to create a unique Binary Tree.
