Algorithmics vs Stepwise

Master data structures & algorithms with an interactive algorithm visualizer — step-by-step execution for coding interview prep. From CS students to FAANG candidates: visualize every approach, compare solutions, and master algorithmic thinking. WHY ALGORITHMICS? Stop memorizing. Start understanding. Watch algorithms come alive through step-by-step visualizations, then explore the same problem solved in different approaches - compare, contrast, and choose your best path. WHAT YOU GET - Algorithm visualizer with interactive step-by-step execution - Many battle-tested algorithms with multiple approaches ready to use - Real interview problems with solution strategies - See which FAANG companies ask each problem and how often - topics and companies at a glance - Every algorithm ships with comprehensive code, tests, visualizations, and documentation - Beautiful syntax highlighting across TypeScript and JavaScript - Three subscription tiers - Basic, Standard, and Pro - Unlock progressively more algorithms, with a free tier to get started HOW IT HELPS YOU INTERVIEW Navigate effortlessly through - Core algorithms organized by pattern with visual demonstrations - Implementations explained through interactive examples - Flip any algorithm card to preview its introduction and description before opening it - Multiple approaches per algorithm showing different paradigms and trade-offs - Navigate between code, tests, visualizations, and documentation with a swipe - Full test coverage to master edge cases BUILT FOR SPEED - Lightning-fast search across everything - Filter by company, topic, difficulty, tier, and language - Check out live stats showing how many algorithms are available and displaying at a glance - Free tier available - start learning with zero barriers WHAT'S INCLUDED TypeScript and JavaScript implementations across pattern groups including Arrays & Hashing, Two Pointers, Sliding Window, Stack, Binary Search, Linked List, Trees, Sorting and more - with real-world examples and algorithm visualizations. PERFECT FOR - CS students and self-taught developers mastering data structures & algorithms - FAANG-style coding interviews and technical interview prep at top tech companies - Visual learners who need to see algorithms in motion - Comparing programming paradigms in action - Quick reference during interview prep Continuously updated with new algorithms, patterns, and languages — built by developers, for developers. Your secret weapon for interview success starts here - visualize it, understand it, master it. Download now and join developers who code smarter, not harder.

Don't watch BFS run. Be BFS. Stepwise is a daily training game for software engineers, built for a phone: tap, drag and swipe. There's no typing on a tiny keyboard. BE THE ALGORITHM Execute real algorithms by hand on freshly generated inputs. Tap nodes in the order breadth-first search visits them, pick which node Dijkstra settles next, sift a value through a heap, probe a sorted array like binary search. Every move is scored, and the puzzles never run out. THE DAILY SET Five challenges, the same for every developer that day. Keep your streak and share a spoiler-free result card. A RATING THAT MEANS SOMETHING Every topic has its own Elo, like chess puzzles. Difficulty adapts to you. MORE GAMES Big-O Blitz, Bug Hunt, Line Up, Output Oracle (Java, Python, SQL), Pick the Structure and Pattern Spotter. There is also an Engineering track: race conditions, SQL traps, index choice. Every answer is checked: generated puzzles take their answer key from the real algorithm, and code snippets are verified by actually running them. Challenge a friend with a link to the exact puzzle you just solved. Your full history is saved, so you can replay anything you missed.
