AlgoLens vs Visulo

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.

Kickstart your Data Structures & Algorithms (DSA) journey with Visulo, a learning companion designed to help you understand the core concepts behind fundamental data structures and algorithms. Whether you're a computer science student preparing for exams, a software engineer brushing up for technical interviews, or a self-taught coding enthusiast, Visulo helps you build a strong foundation so you can confidently start implementing these concepts in code. WHY VISULO? Learning DSA can feel overwhelming when faced with lengthy explanations and textbook-heavy content. Visulo simplifies the process with concise, easy-to-understand theory cards that focus on the essential concepts you need to know before you start coding. KEY FEATURES • BITE-SIZED THEORY CARDS Master important concepts with beautifully designed, scrollable cards that present key ideas in a clear and easy-to-digest format. • KNOWLEDGE CHECK QUIZZES Reinforce your understanding with interactive quizzes designed to help you retain what you've learned. • INTERACTIVE VISUALIZERS Watch algorithms and data structures come alive with real-time, interactive animations. Step through executions, push/pop elements, and traverse nodes to see exactly how the logic works under the hood. MODULES COVERED DATA STRUCTURES: • Binary Trees: Understand tree structures, traversals, and fundamental properties. • Linked Lists: Learn how nodes connect and how lists are traversed. • Queues: Explore First-In, First-Out (FIFO) operations. • Stacks: Understand Last-In, First-Out (LIFO) behavior and applications. ALGORITHMS: • Dijkstra's Algorithm: Learn the core ideas behind shortest-path calculations. • Breadth-First Search (BFS): Understand level-order traversal techniques. • Depth-First Search (DFS): Explore depth-based graph and tree traversals. ...and more topics are planned for future updates! Start building your DSA foundation with Visulo and gain the understanding you need to confidently begin solving problems and writing code.
