Binary Search is a searching technique that works on the Divide and Conquer approach. It is used to search for any element in a sorted array. Compared with linear, binary search is much faster with a Time Complexity of O(logN), whereas linear search works in O(N) time complexity...
In this article, we would be implementing the Binary Search Tree data structure in Javascript. A tree is a collection of nodes connected by some edges. A tree is a non linear data structure. A Binary Search tree is a binary tree in which nodes that have lesser value are stored on the left while the nodes with a higher value are stored at the right....
Binary Search is a searching technique used to search an element in a sorted array. In this article, we will learn about how to implement Binary Search in PHP using iterative and recursive way. Given a array of numbers, we need to search for the presence of element x in the array using Binary Search....
GUI(Graphical User Interface) helps in better understanding than programs. In this article, we will visualize Binary Search using JavaScript. We will see how the elements are being traversed in Binary Search until the given element is found. We will also visualize the time complexity of Binary Search....
Given an array of sorted integers. We need to find the closest value to the given number. Array may contain duplicate values and negative numbers....

An element in a sorted array can be found in O(log n) time via binary search. But suppose we rotate an ascending order sorted array at some pivot unknown to you beforehand. So for instance, 1 2 3 4 5 might become 3 4 5 1 2. Devise a way to find an element in the rotated array in O(log n) time....
Given an unsorted array and a number n, find if there exists a pair of elements in the array whose difference is n. Examples:...
A self-balancing binary search tree (BST) is a type of binary search tree that automatically keeps its height balanced in order to guarantee that operations such as searching, inserting, and deleting elements in the tree take less time on average....
Given an array arr[] and an integer k, we need to print k maximum elements of given array. The elements should printed in the order of the input.Note : k is always less than or equal to n....
Question: Write a function to find if a given integer x appears more than n/2 times in a sorted array of n integers. Basically, we need to write a function say isMajority() that takes an array (arr[] ), array’s size (n) and a number to be searched (x) as parameters and returns true if x is a majority element (present more than n/2 times)....
Given an unsorted array and a number n, find if there exists a pair of elements in the array whose difference is n. Examples:...
