WebAug 3, 2024 · Binary Search Tree. A Binary Search tree has the following property: All nodes should be such that the left child is always less than the parent node. The right child is always greater than the parent node. In the following sections, we’ll see how to search, insert and delete in a BST recursively as well as iteratively. WebBinary Search - Given an array of integers nums which is sorted in ascending order, and an integer target, write a function to search target in nums. If target exists, then return its index. Otherwise, return -1. You must write an algorithm with O(log n) runtime complexity. Input: nums = [-1,0,3,5,9,12], target = 9 Output: 4
