Cozytek Code helps you prepare for coding interviews by learning and practicing reusable data structure and algorithm patterns. Learn core DSA topics through visual lessons and guided practice, including arrays, strings, hash maps, two pointers, sliding window, binary search, trees, graphs, DFS, BFS, backtracking, heaps, greedy strategies, dynamic programming, sorting, and Big-O analysis. Each topic helps you build the reasoning behind a strong interview response: • See how the pattern works • Recognize the signals that point to it • Understand the strategy and key invariants • Build a clear solution outline • Study code examples, edge cases, and Big-O tradeoffs • Practice turning the approach into a structured solution • Track mistakes, accuracy, progress, and mastery The goal is not to memorize one answer. It is to understand the pattern well enough to recognize it across different problems, explain your approach clearly, and structure a solution with confidence. Practice with a growing library of interview-style problems, solution guides, and pattern-focused mastery checks. Add custom interview questions you want to practice, track your own practice metrics, and save problems to revisit through a spaced-repetition review cycle. Full access is available with a premium subscription. Premium unlocks the complete DSA curriculum, practice library, solution guides, mastery checks, custom practice tools, and detailed progress tracking. Your progress, attempts, time, mistakes, accuracy, streaks, and mastery state stay on your device and can sync privately through iCloud when available.
