Solution: Build Binary Tree from Preorder and Inorder Traversal

Solution: Build Binary Tree from Preorder and Inorder Traversal

Let's solve the Build Binary Tree from Preorder and Inorder Traversal problem using the Tree Depth-First Search pattern.

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
