Solution: Build Binary Tree from Preorder and Inorder Traversal

Explore how to build a binary tree from given preorder and inorder traversal arrays. This lesson helps you understand the recursive strategy to identify root nodes and subtrees, optimizing your ability to solve tree construction problems thoroughly.

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 ====
