You’ve just started software, you’re an expert, you’re an intermediate-level developer, or you do not describe yourself as belonging to a group! All is possible! :) But if you are on this path, you know the importance of improving your coding skills. No matter your title or level, it is very important to devote daily time to the software and, most importantly, to the challenge. What do we say about language learning? The language is a living organism and, like a flower, requires taking care of it every day. I will give information about the work and exercises I try to open the boundaries of the brain and change my perspective. First of all, the good news is that there are many sites to practice on, and I have compiled 10 of the most used ones for you!

1. HackerRank: This is one of my favourites! HackerRank offers broad coding challenges across multiple areas, such as algorithms, data structures, artificial intelligence, and more. It provides a platform for both beginners and experienced programmers to improve their skills. Collecting hackos here makes the game better. They’ve got many coding challenges on algorithms, data structures, AI, and more. It’s a cool place for newbies and pros to level up! Plus, you can score certifications and job opportunities.

2. CodeWars: CodeWars is again an excellent platform to hone your problem-solving skills through kata challenges. This is one of my favourites, too! These challenges vary in difficulty level and cover a variety of programming languages, allowing users to solve problems appropriate to their skill level. Be careful of kyus.

3. CodeChef: CodeChef hosts regular coding competitions and challenges for programmers of all skill levels. It provides a supportive community where users can learn from each other, discuss coding problems, and improve their coding proficiency.

4. GeeksforGeeks: GeeksforGeeks is a comprehensive resource for computer science topics and coding interview preparation. It offers a vast collection of coding problems, articles, tutorials, and interview experiences to help users strengthen their coding skills and knowledge.

5. Coderbyte: Coderbyte features coding challenges and interview preparation exercises designed to enhance problem-solving abilities and coding proficiency. It covers various topics, including algorithms, data structures, and programming concepts.

6. LeetCode: LeetCode is a popular platform for practising coding interview questions. It offers many problems categorized by difficulty level and topic, making it an excellent resource for job seekers preparing for technical interviews.

7. freeCodeCamp: freeCodeCamp is a nonprofit organization that offers interactive coding challenges and projects to help users learn web development, data science, and more. It provides a structured curriculum and hands-on coding experience to facilitate skill development.

8. Project Euler: Project Euler is ideal for those interested in mathematical and computational problems. It features challenging mathematical problems that require programming to solve, allowing users to combine their mathematical and coding skills.

9. TopCoder: TopCoder hosts competitive programming contests and challenges covering various algorithms and problem-solving techniques. It offers a platform for users to test their skills against others and improve through practice.
