Construct BST from Preorder Traversal | Python, Java & C++ | With Optimised Solution

How can we construct a Binary Search Tree (BST) from its Preorder Traversal? In this video, we understand the complete approach to building a BST using preorder traversal and the properties of a Binary Search Tree. What you'll learn: How to construct a BST from preorder Understanding the BST property Building the left and right subtrees Using the range / min-max approach Efficient recursive solution Python, Java & C++ implementations Time and space complexity Complexity Time: O(N) Space: O(H) for recursion This is an important BST construction + recursion problem for DSA and coding interviews.
