CodeChef is a not-for-profit educational initiative started by Directi more than a decade ago. We started with a dream of seeing an Indian team winning a gold medal at the ACM ICPC World Finals. In its quest for the same, CodeChef has built a self-driven community of the world's best programmers. Today more than 1.3 million competitive programmers from 180+ countries learn from CodeChef. CodeChef has been hosting monthly programming contests regularly for 10 years now. Its platform has assessed 92 million+ code submissions to date, and over 30000 organizations are being impacted by CodeCheffers worldwide. It also organizes SnackDown - one of the world's largest global programming competition whose last edition drew participation from 140+ countries. Since 2017, CodeChef has started providing India's only industry-ready certification in Data Structures and Algorithms, and 1800+ programmers have been certified under the same.
LeetCode CodechefLeetCode is the best platform to help people practice solving coding problems and prepare for technical interviews. The main users are software engineers. LeetCode has over 1,900 questions covering many different programming concepts.

For those who already know, this is just a reminder, but for those who don't, every week Leetcode has a special contest where a lot of developers try to solve 4 code challenges in a row at 1 hour 30 min. - Source: dev.to / 7 days ago
Firstly, solve some common data structure problems with it. Implement some data structures like arrays, linked lists, stacks, queues, etc. You can check common problems on LeetCode, Hackerank or some other resources. - Source: dev.to / 8 days ago
I did some traveling around the western US in late 2022 to take stock of where my life was and where I was going. During that time I decided that I would go all-in with my coding education, and committed to learning the remaining material listed on those bootcamp syllabi that I had not yet studied – namely, connecting the pieces of the MERN stack; learning about automated testing and data structures & algorithms;... - Source: dev.to / 15 days ago
Practice Regularly: Utilize coding challenge platforms such as LeetCode and HackerRank to practice coding regularly. Additionally, websites like Project Euler offer mathematical challenges that can sharpen your problem-solving skills. - Source: dev.to / 20 days ago
As a self-taught dev, learning the ins-and-outs of Python usually happens as I am solving problems on leetcode or writing random programs in replit. This post is more for myself to remember what I've learned. If you're still interested in reading, then I hope this helps you! - Source: dev.to / 2 months ago
Have you heard of codeforces.com, atcoder.jp, codechef.com, etc? Source: 5 months ago
Leetcode is good to learn basic algorithms because problem statements are usually straightforward. Competitive programming has much wider range of problems. Most popular sites for cp are codeforces.com , atcoder.jp, codechef.com . Source: 5 months ago
Learn Java with hands-on experience. I personally used codingbat.com a lot, but I've heard good things about codechef.com, which appears to even have a competitive option. Source: about 1 year ago
For practicing algorithms, use any of the freely available websites like https://hackerrank.com https://codechef.com https://projecteuler.net A structured set of practice problems are available at https://www.interviewbit.com/courses/programming/ Avoid https://geeksforgeeks.org because it has a ton of material but very poor quality control.

These all have sample problems to solve Hackerrank.com edabit.com codewars.com codechef.com and there are tons more. Best of luck to you. I am at about the same level myself. I really like these sites. Source: about 2 years ago
