💡 Tips for LeetCode

1. Read constraints carefully - They often hint at the solution approach
2. Start with brute force - Then optimize
3. Practice patterns - Group similar problems together
4. Time yourself - Aim for 30-45 minutes per problem in practice
5. Review solutions - Even after solving, read top solutions
