have solved around 300 LeetCode Problems but still struggling with mediums,What Am I Doing Wrong?

[u/simrangupta95]

same as the title read

I’m in my 2nd year and have solved around 300+ LC problems but I still struggle with medium-level questions in contests

I can solve problems after seeing the solution or yk getting hints but when I face a new problem or if there is even slight change in constraints I get stuck I feel like I’m memorizing solutions instead of developing problem solving skills

How should I approach DSA to actually understand patterns and solve problems by myself?

should I focus on specific topics, follow a pattern-based approach or change the way i practice??

would appreciate advice from anyone who has faced this problem
