What it does
CodeChef combines coding courses and career paths with practice problems, competitions and a compiler.
Use the programming and data-structures courses to choose a topic, then move into practice problems that exercise it. The site's separate Practice and Compete areas make it possible to distinguish untimed study from competition. Contest participation is a useful later goal, but the course catalog provides a more directed starting point when the underlying algorithm is still unfamiliar.
