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: about 1 year 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: almost 2 years 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.

Coding Interview Practice Platform: LeetCode (Freemium) LeetCode is one of the most popular platforms for practicing coding problems. Start from the easy questions LeetCode to brush up on coding basics, and gradually move on to the medium questions. It's going to be overwhelming at first even for the easy questions, but we'll usually start to be able to keep up. Spend 10-20 minutes a day for this. We'll see the... - Source: dev.to / 2 months ago
Practice Makes Perfect: Regularly solve coding challenges on platforms like LeetCode (https://leetcode.com/), HackerRank (https://www.hackerrank.com/), and Codewars (https://www.codewars.com/). These platforms provide a wealth of practice problems and help you familiarize yourself with different types of coding challenges. - Source: dev.to / 3 months ago
Project-based learning should, in my opinion, always take precedence. As that part is already covered, I don't find it counterproductive to go deeper into the language and improve my ability to write clean and tidy code. I'm not into the Data Structures and Algorithms part of my studies yet, so I haven't really explored LeetCode too much. I used to practice on Codewars but I always disliked its UI and found it a... - Source: dev.to / 4 months ago
