Binary Search Tree2 Floor and Ceiling of a Binary Search Tree Problem: Given an integer k and a binary search tree, find the floor (less than or equal to) of k, and the ceiling (larger than or equal to) of k. If either does not exist, then print them as None. Here is the definition of a node for the tree. -Summary- 1. if root node is empty we return none value for both floor and ceil. 2. if root node is equal with k, return floor and cell with k value 3. i.. 2020. 6. 19. LeetCode. Search in a Binary Search Tree Problem: Given the root node of a binary search tree (BST) and a value. You need to find the node in the BST that the node's value equals the given value. Return the subtree rooted with that node. If such node doesn't exist, you should return NULL. For example, In the example above, if we want to search the value 5, since there is no node with value 5, we should return NULL. Note that an empty t.. 2020. 6. 16. 이전 1 다음
