Solution: Build Binary Tree from Preorder and Inorder Traversal

Explore how to build a binary tree from given preorder and inorder traversal arrays by using recursive techniques. Understand how to identify root nodes and divide left and right subtrees effectively. This lesson helps you master tree reconstruction while optimizing time and space complexity.

We'll cover the following...

Statement

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

Constraints:

  • 1≤1 \leq pOrder.length, iOrder.length ≤1000\leq1000
  • iOrder.length ====
