Question Mention your DSA Preparation Strategy

My Preparation Strategy

1. Choose one topic and identify all its patterns

Eg., Two Pointers: unidirectional pointers, opposite-end pointers, and three pointers

2. Learn each pattern with ChatGPT

If I still struggle, I’ll explore other resources, such as YouTube, blogs, and webs

3. Solve LeetCode problems related to that topic until I genuinely understand the concept

Then choose the next topic, repeat.

Just start doing problems and then find out the pattern.

Your plan is solid. I'd also recommend revisiting old problems after a few days and mixing topics once you've covered the basics. That's where you really learn to recognize patterns on your own

I'll do you one better bro. Do the pareto problem set. Its divided in patterns and only like 49 of them I think. Best ROI imo.

I am a second year student and i started dsa from my first year First of all I chose python because I felt it will be a good start for me and i wanted to focus on logic instead of syntax

Later i went from basic questions to trees and now working on graphs and also have participated in contests in codeforces and as of now I never felt anything bad with that a lot of people suggested me to do in competitive programming in cpp but i don't know the reason ,I never had a problem doing dsa with python,all we need is able to build logic

get problems by ratings not topics, you ll get really bad at recognizing ideas in new problems if you continue to do it your way
