1. You are given a partially written function to solve(Refer question video). 2. Task : Construct Binary Search Tree from given PreOrder Traversal. 3. you will be given an array representing a valid PreOrder of a Binary Search Tree. Program is required to create a unique Binary Search Tree.
Input Format
Input is managed for you.
Output Format
Output is managed for you.
Constraints
0 <= Number of Nodes <= 10^9 -10^9 <= value of Node data <= 10^9 Valid PreOrder traversal.
Notice
Try First, Check Solution later
1. 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.Example
Input
