Build Binary Tree from Preorder and Inorder Traversal

Explore how to build a binary tree from given preorder and inorder traversal arrays. Understand the relationship between these traversals and apply depth-first search strategies to reconstruct the tree efficiently. This lesson helps you grasp essential binary tree concepts and coding patterns valuable for technical interviews.

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
