AlgoLens teaches coding patterns the way they actually click — through real-world stories, interactive visualizers, and guided practice. Instead of memorizing abstract algorithms, see why and where each pattern is used in real software systems: • Fraud detection → Sliding Window • Duplicate payments → HashMap • Undo / Redo → Stack • Recently Played → Arrays • Friends of friends → Graph BFS • Calendar conflicts → Merge Intervals Eight pattern paths so far: • Arrays • HashMaps • Two Pointers • Sliding Window • Stack & Queue • Trees • Graph Basics • Merge Intervals Each lesson includes: • A real-world story that anchors the pattern in memory • An interactive visualizer — step through, play, watch the work happen • Guided practice problems with explanations • An interview-ready breakdown with time/space complexity, vs. brute force, and a Swift code sample in a syntax-highlighted editor Practice mode adds three coding game types: • Fill in the blanks — tap a token, drop it into the right slot • Sort the code — shuffled lines, tap two to swap them into order • Find the bug — read the function, tap the line that doesn't match the title Stack streaks, earn XP, and filter puzzles by the companies that ask similar questions in interviews — Google, Meta, Apple, Amazon, Microsoft. Built for mobile-first learning. iPhone-sized, dark code editor styling, short focused lessons designed for the in-between moments. Understand patterns visually. Remember them through stories. Apply them like real engineers.
