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 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: 6 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: over 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: over 2 years ago
Project Euler: Solve math and programming puzzles that help you think logically and improve your problem-solving skills. - Source: dev.to / 5 days ago
With this newfound perspective, I embarked on a new path. I decided to tackle problems from Project Euler, solving them at scale and under various constraints. It is my hope that this approach will not only provide practical challenges but also allow me to apply and solidify my programming knowledge in a more engaging way. - Source: dev.to / 18 days ago
Could solve Project Euler problems in Lua - aka, the easiest programming language to learn https://projecteuler.net/ Alternatively, you could get a homeschool math textbook. They're written differently because the assumption is that the kid is going to have to teach themselves, and as such they are significantly more thorough and easy to understand. I highly recommend them. Don't get the kind that are "workbooks",... - Source: Hacker News / 27 days ago
