## What is AlgoLens?

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.
