## What is Coduzzle?

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.
