Data Structure Binary Tree: Construct Full Binary Tree from given preorder and postorder traversals 1#include <iostream>2#include <vector>3#include <algorithm>4#include <queue>5#include <stack>6#include <string>
Preorder traversal pre[] = {1, 2, 4, 5, 3, 6} Output: Postorder traversal is {4, 5, 2, 6, 3, 1} A naive solution is to first construct the given tree, then recursively traverse it in post order. A better solution is to acheive this without having to construct the given tree...

The time complexity of the above solution isO(n), wherenis the size of the BST, and requires space proportional to the tree’s height for the call stack. Also See: Build a Binary Search Tree from a preorder sequence Build a Binary Search Tree from a postorder sequence ...
