Solution: Build Binary Tree from Preorder and Inorder Traversal

Understand how to build a binary tree from preorder and inorder traversal arrays by identifying root nodes and dividing subtrees recursively. This lesson covers using DFS techniques and hash maps for efficient tree construction with clear time and space complexity insights.

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 ====
