Build Binary Tree from Preorder and Inorder Traversal

Explore how to construct a binary tree by leveraging preorder and inorder traversal arrays. This lesson helps you understand tree traversal principles and implement efficient binary tree reconstruction, essential for solving common coding interview problems.

We'll cover the following...

Statement

Create a binary tree from two integer arrays, p_order and i_order, where p_order represents a preorder traversal of a binary tree, and i_order represents an inorder traversal of the same tree.

Constraints:

  • 1≤1 \leq
