Build Binary Tree From Preorder and Inorder Traversals
Medium
Construct a binary tree using arrays of values obtained after a preorder traversal and an inorder traversal of the tree.
Example:
Input: preorder = [5, 9, 2, 3, 4, 7], inorder = [2, 9, 5, 4, 3, 7]
Constraints:
- The tree consists of unique values.
