One of the best way to improve the coding skill of a programmer while learning is to solve more and more coding challenges. Solving different types of Coding Challenge and practices will help the programmer to become a better problem solver. It will also help the programmer to learn more details about it. The IT professionals can also prepare for their job interviews by practicing coding on the websites. As most of the big IT companies use these online coding platforms to check programmers skills. It will also help the programmers to learn new algorithms and use them to solve a problem.
So, here is a list of 10 Best and popular coding websites for live Coding Challenges.
TopCoder is the first website on our list of 10 Best websites for live Coding Challenge. It is also one of the first and original platforms for competitive programming online. The website provides a list of algorithmic challenges to the user for practicing. The programmer can complete these challenges on their own directly using the website’s code editor.
The website also offers the popular Single Round Matches few times in a month at a specific time. Using these matches, a programmer can compete with other programmers around the globe to solve challenges fastest to get the best score.
HackerRank is also one of the widely used websites for Coding Challenges online. HackerRank provides several different types of challenges to the programmers. The challenges are from several different domains such as Algorithms, Mathematics, SQL, Functional Programming, AI, and more. It also allows the programmer to solve these challenges directly online. The website also provides a discussion and leaderboard for every challenge where programmers can discuss the challenge. The leaderboard provides the list of those programmers who solves the challenge fastest.
Also, most of these challenges contain an editorial that provides more information about the challenge. It also explains how the programmer has to approach in order to solve the challenge. The programmers can also view the solution of the other users on the website. HackerRank also allows users to submit applications and apply for jobs by solving some company-sponsored coding challenges.
The next website on the list of 10 Best websites for live coding online is CodeChef. CodeChef is an Indian-based competitive programming website that provides more than hundred challenges to the programmers. Like most of the websites on the list, it also allows programmers to write code in its online editor.
CodeChef also provides a collection of challenges to the programmers separated into different categories. A programmer can choose any of the categories depending on their skill level. CodeChef has a large community of coders that contribute to various forums of the website. There are also tutorials available on the website by the coders.
Coderbyte is the next website on our list of 10 Best websites for live Coding Challenge. It provides more than 200+ coding challenges to the programmers. A programmer can directly solve these coding challenges online in any of the 10 programming languages that the website offers. Coderbyte also allows the programmers to select the challenge difficulty according to their convenience. The programmer can start from the easiest challenge (finding the largest word in a string) to hard challenge (print the maximum cardinality matching of a graph).
The website also provides a collection of algorithm tutorial to the programmers. It also contains some introductory videos that programmer can use to know more about Java. Coderbyte also provides some interview preparation courses for job seeking programmers. The website also allows programmers to view the solution that other users provide for any particular challenge.
Codewars is also one of the best websites for practicing online Coding Challenge. Codewars provides a large collection of coding challenges that a programmer can solve. These challenges are submitted and edited by the community members of Codewars. It also allows the programmers to solve the challenges directly online in the editor. Programmers can also select any language from the list of several languages.
The next website on the list is CodeEval. CodeEval is just like the HackerRank as it also provides a collection of company-sponsored coding challenges to the programmers. These challenges can help the programmers to get a job if the programmer can solve all the challenges. The website also allows companies to create various challenges and host some competitions through it to recruit new developers for work.
LeetCode is also one of the popular and widely used websites for practicing coding challenges online. It is just like an Online Judge that provides more than 190+ challenges to the programmers. These challenges help the IT professionals to prepare for technical job interviews. Just like most of the websites, LeetCode also allows programmers to solve the given challenge directly on the website. The website allows the programmers to choose any of the 9 programming languages for practicing the coding. Although, the website does not allows programmers to view the solutions of other users, but the programmer can get the statistics for their own solution.
CodinGame is the next website on the list of 10 Best websites for online Coding Challenge. It is a bit different from most of the other websites on the list. In CodinGame instead of simply just solving the coding challenges using an editor, the programmer has to actually take part in writing the codes for a game that user can play directly online. The programmer will see a list of games on the website and they can select one from the list. These games come with a problem description, some test cases, and also an editor where the programmer has to write the code. It also offers support of more than 20+ programming languages. So, the programmer can select any of these languages to code on.
Project Euler is also one of the best websites live Coding Challenge online. It contains a large collection of challenges that a programmer can solve. These challenges are mainly in the domain of computer science and mathematics. In most of the challenges, the user has to write a small program to get the solution of a mathematical formula or an equation.
Sphere Online Judge (SPOJ) is also an online website that programmers can use for online Coding Challenges. It provides more than 20 thousand coding challenges to the programmers. Like most of the online websites, it also allows programmers to submit their code in an online editor. Sphere Online Judge (SPOJ) also hosts some contests. It also has an area where the programmers can discuss the coding challenges of the website. However, unlike most of the websites, SPOJ currently does not provides any official solution for a particular challenge.
Online website offers more programming comfort-ability to the programmers. These websites are also very easy to use. A user has to just open the website, create an account on the website. After that, they can start coding by just signing on the website. Also, the websites provide different varieties of challenges to the programmers. So, I hope that the readers will find this article useful for themselves in selecting the best website for live Coding Challenge.
