CodeChef

Competition might be the most effective incentive for learning, and CodeChef offers that. This India-based website is one of several that allow users to test their abilities against other coders in challenging contests, offering great coding exercises for beginners.

CodeChef is a platform and online community where software developers may solve practice challenges to prepare for technical interviews. CodeChef can be broken into two main sections: CodeChef Practice and CodeChef Compete. It has thousands of challenges and user solutions, so you'll never run out of problems to practice on. The challenges, which range in difficulty from basic to advanced, test users' knowledge of algorithms, binary search, array size, and a number of other DSA subjects. To gradually increase the difficulty, coding challenge sites use a ranking system that categorizes from easy to difficult. Each challenge is also labeled with its topic to help in categorizing and searching for different types of difficulties.

For user submissions, CodeChef supports over 35 languages. Users earn badges as they accomplish tasks, which help them advance in the CodeChef rankings as they move on to more difficult challenges. There are around 3000 practice problems in various difficulty levels in many algorithmic topics. CodeChef makes it simple for users to choose challenges that correspond with specific expertise and ideas.
