A curated pattern-based approach to cracking DSA interviews. No fluff. No randomness. Just the 289 problems that matter, organized by the patterns that make them click.
Pattern-First Learning
Stop grinding random problems. Learn to recognize patterns, and every new problem becomes a variation of something you already know.
Learn the Pattern
Master recognition signals, core templates, and common traps. Don't memorize; understand the underlying structure.
Solve with Purpose
Progress from intro to standard to twist. Each problem is carefully selected to teach a specific concept.
Build Recognition
Track your mastery per pattern. Over time, you won't just solve problems—you'll see the solution instantly.
0 Patterns Across 0 Sections
From Two Pointers to Dynamic Programming, every pattern you need for any DSA interview.
Built Different.
Not another random LeetCode list. A system designed for deep pattern recognition and long-term retention.
Pattern-First Organization
Problems grouped by patterns, so recognition becomes automatic.
Structured Progression
Intro → Standard → Twist. Build confidence before complexity.
Track Every Pattern
Know what’s mastered and what’s next, at a glance.
Solve on LeetCode
Direct links to problems. Solve there, track here.
No Bloat, No Paywall
Curated problems only. Everything stays free forever.
Learn the pattern, then solve everything in it.
Each pattern comes with a core idea and a curated set of problems across difficulties.
