Determine if tree is binary search tree

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. WebJun 24, 2024 · Copy. First, we need to consider the case if our node is null: we'll return true (which means the tree is balanced) and -1 as a height. Then, we make two recursive calls for the left and the right subtree, keeping the depth up to date. At this point, we have calculations performed for children of a current node.
