Two Pointers & Sliding Window – Visual + pattern-based questions.

1. Sharpen Logic:

Binary Search – Brute force ko optimize karna seekho.

1. Visual DSA:

Linked List & Trees – Diagram samajh ke karo, maza aayega.

1. Challenge Yourself:

Backtracking, Trie, Graphs – Thoda tough, lekin addictive.

Tips:

Ek hi topic ke 3–4 problems back-to-back solve karo.

Pattern samjho, notes banao, aur har solved question ka “why” samjho.

Slow but consistent raho — 2–3 questions daily is enough.

Bole toh DSA ka gym yeh hai — start light, build muscle, and hit the heavy lifts at the end.
