Binary Search is a searching algorithm for finding an element's position in a sorted array. In this tutorial, you will understand the working of binary search with working code in C, C++, Java, and Python.

When we put those numbers in a binary search tree, we only need average(1 + 2 + 2 + 3 + 3 + 3 + 3) / 7 = 2.42 comparisons to find the number. The Binary Search Tree 's search algorithm is roughly O(log2n) However this is the best-case . ...

Hence we deduced that 9 did not exist in the BST.Analyzing the BST Search AlgorithmFor finding a node in a BST, at each stage we ideally reduce the number of nodes we have to check by half. For example, consider the BST in Figure 6, which contains 15 nodes. When starting our search...
Given an integer array nums where the elements are sorted in ascending order, convert it to a height-balanced binary search tree. A height-balanced binary tree is a binary tree in which the depth of the two subtrees of every node never differs by more than one. ...
