Binary tree divide and conquer
WebIn the case of a binary tree level order traversal, we can think of the divide and conquer problem as having to split the problem of a node dealing with its children into two … WebThe time complexity of the above solution is O(n), where n is the size of the BST, and requires space proportional to the tree’s height for the call stack.. Another approach: We know that an inorder traversal of a binary search tree returns the nodes in sorted order. To determine whether a given binary tree is a BST, keep track of the last visited node …

WebAug 3, 2016 · @shole Assuming you are working with integers, if you use a van Emde Boas tree instead of binary search, it can be done in O(n * lg(lg(n))) time, and with additional key renaming (as described here), it can be reduced to O(n * lg(lg(k))) time, where k is the length of the LIS. As far as I know, this is the fastest known algorithm.
