WebDSA question curated especially for you! Q: Given a binary tree, check if it is a valid binary search tree (BST). Input: [2,1,3] Output: True Logic: A valid BST is a tree in which each node's left ... WebBinary search is an efficient algorithm for finding an item from a sorted list of items. It works by repeatedly dividing in half the portion of the list that could contain the item, until you've narrowed down the possible locations to just one. We used binary search in the guessing game in the introductory tutorial.
