WebYou are given a BST (Binary search tree) with’ N’ number of nodes and a value ‘X’. Your task is to find the greatest value node of the BST which is smaller than or equal to ‘X’. Note :‘X’ is not smaller than the smallest node of BST . For example: WebGiven a Binary Search Tree and a target sum. Check whether there's a pair of Nodes in the BST with value summing up to the target sum. Example 1: Input: 2 / \ 1 3 sum = 5 Output: 1 Explanation: Nodes with value 2 and 3 sum up to 5. Example 2: Input: 6 / 5 / 3 / \ 1 4 sum = 2 Output: 0 Explanation: There's no pair that sums up to 2. Your Task:
Binary Search Tree - LeetCode
WebMar 23, 2024 · Flatten BST to sorted list Increasing order. Given a binary search tree, the task is to flatten it to a sorted list. Precisely, the value of each node must be lesser than the values of all the nodes at its right, and its left node must be NULL after flattening. We must do it in O (H) extra space where ‘H’ is the height of BST. WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. how many days does parvo last
