Master coding interview patterns through understanding, not memorization. Free problems included — unlock the full pack to level up. Coduzzle teaches you to recognize coding interview patterns through a structured 5-step learning loop — so you understand WHY solutions work, not just what they're called. Each problem guides you through: • Read the problem and tap clue words that hint at the approach • Select the building blocks (data structures, variables) the solution needs • Arrange strategy steps in the correct logical order • Review the full explanation with time/space complexity • Identify the algorithmic pattern — after you already understand it Covers Sliding Window and Binary Search patterns with problems ranging from Easy to Medium difficulty. 3 problems free, with optional monthly ($0.99/mo) or annual ($9.99/yr) subscriptions to unlock all problems. Built for anyone preparing for software engineering interviews who wants structured, active practice on their phone — no laptop required.
