Learn how to reconstruct a binary tree from its preorder and inorder traversals. The key insight: preorder's first element is always the root, and finding that root in inorder splits the left and right subtrees. We walk through the divide-and-conquer approach step by step, then implement it in code — first O(n²), then optimized to O(n) with ...
