Solution: Build Binary Tree from Preorder and Inorder Traversal

Explore how to build a binary tree from preorder and inorder traversal arrays by using the root selection and subtree division approach. Understand the recursive method to construct subtrees and learn the time and space complexity involved in this process.

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
...
