How to use LeetCode Efficiently

1. Start with the basics: Begin with easy problems and build up your knowledge of algorithms and data structures. Focus on understanding the concepts, not just getting the right answer.
2. Set a goal: Decide how many problems you want to solve each day and stick to that number. This will help you maintain a consistent pace and keep you motivated.
3. Use multiple approaches: Try to solve each problem using different algorithms and data structures. This will help you understand the pros and cons of different approaches and make you a better problem solver.
4. Time yourself: Make sure to time yourself for each problem and track your progress. This will give you an idea of how long it takes you to solve a problem and help you identify areas where you need to improve.
5. Use the discussion forums: The discussion forums are a great resource for learning new solutions and understanding different approaches to problems. Don’t be afraid to ask questions and engage in discussions with others.
6. Practice, practice, practice: The more you practice, the better you will get. Make sure to review your solutions and understand why a particular approach is better or worse than others.
7. Keep learning: LeetCode is just one resource for improving your coding skills. Make sure to read books, blogs, and articles on algorithms and data structures to deepen your understanding.

By following these tips and dedicating 30 minutes to an hour each day, you should be able to make significant progress on LeetCode and become a better problem solver.
