What it does
HackerEarth Practice groups programming problems into basic programming, data structures, algorithms and mathematics.
Choose a topic before selecting a problem from the table. Difficulty and acceptance information help you find an exercise to attempt, while the subject labels keep practice focused. The separate mock-assessment area serves a different goal from learning a new algorithm. Start with a topic you can explain, then use a harder problem to expose where that explanation breaks down.
Strengths
- Problems are organized by technical topic and difficulty
Best for
- Focused algorithm and data-structure practice
