Whether you’re just starting out as a coder or want to advance your coding skills, tackling programming problems is part of the plan.
Coding problem websites test your skills with customized exercises, friendly challenges, and insightful evaluations. They’re convenient, free, and even enjoyable.
Practicing your coding through these websites may increase your knowledge, build your skills, and prepare you for programming job interviews.
Coding is not a spectator sport. It’s great to watch tutorials and read books on code but to truly develop your programming proficiency, you need to write the language for yourself.
Here are some of the best places for you to practice your newfound coding skills.
You might be unsure of what to practice initially when you start to build your coding abilities. Working on actual issues that other programmers have encountered in the real world is beneficial, and Coderbyte offers this. You can refine your abilities on real-world instances with the help of the more than 300 issues on front- and back-end development, data structures, and algorithms that software professionals have encountered in their interviews.
Coderbyte also lets you use 16 different programming languages and has a library of over 2 million user-submitted solutions, giving you all the practice you need.
TopCoder is one of the original platforms for competitive programming online. It provides a list of algorithmic challenges from the past that you can complete on your own directly online using their code editor. Several times a month, at a set time, they provide their well-liked Single Round Matches, in which you compete with others to complete tasks as quickly as possible while scoring the highest.
The top-ranked users on TopCoder are very good competitive programmers and regularly compete in programming competitions. The top-ranked user maintains his own blog titled Algorithms weekly by Petr Mitrichev where he writes about coding competitions, algorithms, math, and more.
HackerRank is one of the most popular competitive programming websites available, even though it is intended for users with some prior coding experience. This coding community can demonstrate how your programming compares to the field through online challenges and leaderboards that display your position.
It’s not all a contest, though; HackerRank supplies you with plenty of tutorials and explanations to strengthen your skills — and since it’s designed to help developers get noticed by top tech companies, it may end up landing you a job.
It makes sense that the Codewars platform would have a martial arts theme because programming is both an art and a science. As you gain programming knowledge, you can advance in the ranks by completing community-generated challenges or katas in one of 29 programming languages of your choice. When you reach mastery, you can impart your expertise to other students.
Multiple-choice and peer-reviewed programming challenges can be found on Geektastic. Each answer to a multiple-choice question is accompanied by a thorough explanation. You can develop and share your own challenges with their global community in addition to taking on theirs. If you achieve a certain ranking, you may even be requested to join their elite review team, which is comprised of individuals that analyze code challenge submissions for some of the fastest-growing tech businesses in the world while on the side for pay.
Finish the coding challenges, then create projects for charities. This free online coding community offers tutorials to learn several programming languages and offers a ton of interactive practice opportunities. To assist users in gaining experience and ultimately finding employment as developers, the website collaborates with organizations. Additionally, freeCodeCamp provides validated credentials.
With more than 25 supported languages, CodinGame provides challenge-based programming training through games, puzzles, and competitions.

The best way to learn is through competition, and CodeChef provides just that. This platform, which is located in India, is one of many that allow users to prove their coding prowess in difficult competitions with other programmers. This gives novice programmers lots of practice. However, as participants frequently create postings and tutorials to aid one another in learning, the rivalry is amicable.
9. Project Euler
Project Euler offers a chance to solve challenging math problems with the script. While you can’t write your program directly into their editor, you can gain hands-on math and coding experience all in one.
The top platform for developing your coding abilities is LeetCode. It provides a variety of coding challenges. It provides competitors with a variety of weekly and biweekly programming competitions. In most cases, the competitions last 90 minutes. In their own online editor (called Playground), you can solve the puzzles using any of the supported programming languages. On LeetCode, in addition to the Coding Contest, there are a number of other services available, including forums and resources for preparing for job interviews.
Face off against more than three million other developers globally. Participate in monthly coding competitions that range in difficulty from beginner to expert. HackerEarth’s platform is accessible to developers for free, and it supports over 35 different programming languages. Developers can learn and assess their performance by completing more than 100 problems in each of the practice tracks, which include Data Structures, Algorithms, and others, and ranking on the scoreboard.
It takes a lot of patience to program. Start competing in programming contests, and you’ll start to get better every day. Displaying your ranking on your CV will also help you get a job at a top tech company.
