Features

Visualizer

• Live pointer flags with color-coded chips
• Bar states: unsorted (indigo), comparing (cyan), pivot (amber), sorted (green)
• Squash-and-bounce swap animation
• Sound mode — pitch mapped to bar value (220–880 Hz); square wave for swaps, sine for compares
• Confetti on completion
• Scrollable step history with JSON/CSV export
• Custom array input (comma or space separated, up to 100 values)
• Duplicate-value detector with one-click fix
• Worst-case generator for the active algorithm
• Share link + iframe embed snippet
• Per-algorithm speed memory across tab switches

Compare / Race Mode

• Race — all five algorithms run simultaneously with a live leaderboard
• Versus — head-to-head between any two algorithms
• Race history persisted in localStorage (last 10 runs), replayable
• Export any race as JSON or CSV

Quiz Mode

Three escalating tiers:

1. Pattern Recognition (1pt) — Identify, Predict
2. Applied Understanding (2pt) — Trace, Bug-finding
3. Deep Reasoning (3pt) — Reorder pseudocode, Trade-off questions

Every answer reveals an explanation panel. Score, streak, and best streak are tracked.

Sort DNA

A session personality engine in the footer. Tracks algorithm switches, steps advanced, pseudocode reads, races run, and dwell time, then reduces these into four 0–100 scores: Curiosity, Speed, Breadth, Race. Combined, these produce a personality label (e.g. Explorer, Speedrunner, Completionist).

Embeddable Widget

A chrome-free version at /embed, meant to be dropped into blog posts or teaching pages via <iframe>.
