You may wonder how you can increase your coding and programming skills. 

Solving various types of coding tasks on a regular basis will help you enhance your coding abilities. It’s a good idea to run through a lot of practice problems to strengthen your understanding of how the code should work.

But where can one find such a coding challenge?

Luckily, there are some excellent websites for improving your programming and coding skills by tackling challenging puzzles and challenges in any programming language you’ve used.

Actually, several of these websites have competitions on a regular basis, so if you’re good with your codes, you might be able to win some cash.

1. HackerRank

One of the greatest learning and competition communities for programmers is the HackerRank Community. They provide exercises for Python, Java, SQL, C++, Linux Shell, and a variety of other topics. By completing HackerRank challenges, you will be able to master new programming topics and techniques. Many challenges will include a contest between your bots and other hackers’ bots, so may the best hacker win.

Of course, you can also take the easy route and have someone do a Javascript static analysis of your code. 

2. CodeChef

CodeChef was established as a platform to assist programmers in breaking into the field of algorithms, software development, and programming competitions. Directi, an Indian software firm and a global programming community, has launched a non-profit educational effort that promotes learning and friendly competition.

3. Codeforces

Codeforces is a Russian website devoted to programming competitions. They offer a variety of services, including participation in brief (2-hour) contests, the option to challenge/hack other participants’ solutions, and the chance to solve problems from prior contests for training reasons.

4. Exercism

Exercising is another way to improve your coding and programming skills. The exercises are appropriate for both novice and experienced programmers. You can practice tasks in 30 different programming languages by downloading them.

5. Spere Online Judge

SPOJ (Sphere Online Judge) is a problem-solving system with over 200,000 users and 20,000 cases. The tasks are either created by their community of issue solvers or taken from prior programming competitions. SPOJ allows advanced users to create their own contests with their own set of rules, as well as a forum where programmers may discuss how to tackle a certain challenge.

6. Project Euler

Project Euler is a collection of difficult mathematical and computer programming tasks that will necessitate more than just mathematical knowledge to accomplish. Although mathematics will aid in the development of beautiful and effective approaches, most problems will necessitate the use of a computer and programming expertise.

7. CodeEval

Developers can utilize CodeEval to demonstrate their abilities. Developers can compete in app development competitions for cash and prizes. They can also complete programming challenges to demonstrate their technical abilities to potential employers.

8. CodingBat

CodingBat is a free website with live coding issues to help you improve your Java and Python coding skills. CodingBat tasks are excellent for homework, self-study practice, labs, and live lecture examples.

9. Google Code Jam

Google Code Jam is a Google-hosted and managed international programming competition. The competition consists of a set of algorithmic challenges that must be solved within a defined time limit. Competitors may design their ideas using any software language and development environment.

10. TopCoder

Topcoder is the largest community of competitive programmers, developers, and data scientists in the globe. Topcoder sponsors online competitive programming contests every two weeks (known as SRMs or “single round matches”), as well as weekly graphic design and development challenges.

11. LeetCode Online Judge

LeetCode OJ is a platform for technical coding interview preparation. Choose from a growing library of over 190 questions, code your answer, then submit it to see whether you got it right.
