Solution: Build Binary Tree from Preorder and Inorder Traversal

Discover how to build a binary tree from preorder and inorder traversal arrays. Learn to identify root nodes, divide subtrees, and apply recursion to reconstruct the entire tree. Understand the process flow and analyze time and space complexity for an optimized solution.

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 ====
