Editorial Review
LeetCode is the dominant platform for competitive programming practice and software engineering interview preparation, offering thousands of problems categorised by difficulty, topic, and company, with a built-in online judge. The free tier provides access to a substantial problem set, and the premium tier unlocks company-specific problem lists and editorial solutions. It is indispensable for CS students preparing for industry technical interviews, though its use-case is narrow and it offers no curriculum integration or teacher tooling.
