Algorithms Arena is a game-shaped data structures and algorithms course for technical interviews and computer science study. WATCH, PREDICT, PERFORM Every lesson is powered by a deterministic execution trace. Scrub through the animation, predict the next operation, then take control of the board and perform each compare, swap, visit, or table update yourself. A COMPLETE PATTERN ROADMAP Study 17 chapters spanning Big-O, arrays and hashing, two pointers, sliding windows, stacks and queues, binary search, linked lists, trees, tries, heaps, backtracking, graphs, dynamic programming, greedy algorithms, intervals, and bit manipulation. BUILD INTERVIEW INTUITION Use daily five-minute drills scheduled from the skills that need review. Learn to recognize patterns, assemble approaches, find edge cases, check invariants, and call time and space complexity under pressure. RACE BIG-O Compare growth curves, rank complexity classes, test an operation budget, and run capped native benchmarks on your own Apple device. USE YOUR OWN DATA Supply a bounded array, graph edge list, or string. Bundled offline algorithms generate a fresh visual trace locally—your input is data, never downloaded code. MORE WAYS TO MASTER THE MATERIAL • 280 enriched seven-stage lessons • 900 animated traces across 100 canonical algorithms • 1,600 interview drills across six formats • 480 four-language complexity cases • CodeBuild token exercises and 17 chapter boss battles • Per-pattern ranks, XP, streaks, streak freezes, and crowns • Sorting Gallery and optional Game Center leaderboards • Pseudocode, Swift, Python, and JavaScript listings • Apple Pencil scratch layer on iPad and keyboard controls on Mac PRIVATE BY DESIGN Algorithms Arena has no account, no advertising, no analytics, and no tracking.
