Binary search is a fast search algorithm with run-time complexity of (log n). This search algorithm works on the principle of divide and conquer, since it divides the array into half before searching. For this algorithm to work properly, the data collection should be in the sorted form....
In this lesson we learn how to implement a Binary Search Algorithm usingTypeScript / Javascript, and we describe the problem that it solves. function binarySearch( array: number[], element: number, start: number=0, end: number= array.length -1): number {if(end <start) {return-1; }cons...
In this article, we'll look at the idea behindBinary Searchand how to implement it in JavaScript. Binary Search is a very simple, intuitive, yet efficient searching algorithm. The only caveat is that it works only sorted arrays, so some preprocessing on our data in order to sort it might...
Binary Search Algorithm: In this tutorial, we will learn about the binary search algorithm, and it's time complexity in detail and then, implemented it in both C & C++. As a follow up there are several use cases or variations of binary search. By Radib Kar Last updated : August 14,...

As a quick re-introduction, a binary search algorithm works by evaluating a value in a set and determining if it is equal to, less than, or greater than the value for which you’re searching. If the value to find is less than the value being checked, then the search must continue in...
