Solution: Build Binary Tree from Preorder and Inorder Traversal
Understand how to build a binary tree by leveraging preorder and inorder traversal arrays. This lesson guides you through a depth-first search approach using recursion to identify root nodes and split subtrees efficiently. You'll learn to implement the recursive algorithm with optimal time and space complexity, preparing you for coding interviews involving tree traversal problems.

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:
-
pOrder.length,iOrder.length
