Write a JavaScript program to find the first index of a given element in an array using the ternary search algorithm. A ternary search algorithm is a technique in computer science for finding the minimum or maximum of a unimodal function. A ternary search determines either that the minimum or ...
Depth first search is a graph search algorithm that starts at one node and uses recursion to travel as deeply down a path of neighboring nodes as possible, before coming back up and trying other paths. const {createQueue} = require('./queue');functioncreateNode(key) { let children=[];re...

In this article, we have seen the logic behind linear search, and then using that knowledge, we implemented the algorithm in JavaScript. We have also looked at the time complexity for the linear search algorithm. It's by far the simples search algorithm, one that doesn't use any logic to...
If we look for ‘a’, the algorithm will only look at the first element and return, so it’s very fast.But if we look for the last element, the algorithm needs to loop through all the array. To calculate the Big O value we always look at the worst-case scenario....
This article will show users the widely used technique of binary search inJavaScript. What is Binary Search? The binary search is an algorithm that splits the array approximately in half every time it checks or goes through the array element and checks whether the element exists in the JS arr...
At this stage, we are left with no unmarked (unvisited) nodes. But as per the algorithm we keep on dequeuing in order to get all unvisited nodes. When the queue gets emptied, the program is over. Let's look at how we can implement this in JavaScript. ...

A星寻路算法(A* Search Algorithm) 你是否在做一款游戏的时候想创造一些怪兽或者游戏主角,让它们移动到特定的位置,避开墙壁和障碍物呢? 如果是的话,请看这篇教程,我们会展示如何使用A星寻路算法来实现它! 在网上已经有很多篇关于A星寻路算法的文章,但是大部分都是提供给已经了解基本原理的高级开发者的。
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; ...
