About this app
DSAlgo is the ultimate visual learning companion for computer science, coding interviews, and software engineering. Visualize data structures, algorithms, system design, programming languages, and git commands in real-time with step-by-step interactive animations, code tracing, and voice narration.
Struggling to visualize complex code? Staring at dry textbooks?
DSAlgo brings computer science concepts to life. Whether you are preparing for coding interviews at top tech companies, studying for university exams, or sharpening your software engineering skills, DSAlgo makes mastering programming structures and system design easy, engaging, and fun!
🔍 WHAT YOU GET - 358 topics across 13 categories:
• 126 Algorithms (22 categories): Sorting (Merge, Quick, Heap, Radix, etc.), searching, graph traversals (BFS, DFS, Dijkstra, Prim, Kruskal), dynamic programming (26 topics), greedy, backtracking, recursion, string matching (KMP, Rabin-Karp, Z-algorithm), bit manipulation, matrix ops, intervals, and geometry.
• 23 Data Structures (99 operations): Arrays, Stack, Queue, Linked Lists, BST, AVL Tree, Red-Black Tree, Heaps, Trie, Segment/Fenwick Trees, Bloom Filter, LRU/LFU Cache, Disjoint Set, and Suffix Array. Watch operations animate live.
• 21 Design Patterns: All Gang of Four (GoF) creational, structural, and behavioral patterns with interactive UML class diagrams.
• 20 LLM Architecture & AI topics: Tokenization (BPE), embeddings, attention layers, transformer blocks, sampling, KV cache, RoPE, quantization, MoE, RAG pipelines, AI agent loops, vector DB indexing (HNSW), and prompt engineering.
• 33 System Design topics: REST API, Load Balancers, CDN, OAuth 2.0, Rate Limiter, DB Replication, Message Queue, Caching, Sharding, Consistent Hashing, Kubernetes, Raft, Saga, S3, gRPC, and Elasticsearch.
• 14 DBMS topics: B-Tree index, ACID transactions, replication, query optimization, connection pooling, and SQL (JOINs, Window functions, CTEs).
• 12 Networking topics: TCP handshake, reliable transport, DNS, HTTP lifecycle, TLS, L2 switch, L3 router, NAT, ARP, and DHCP.
• 9 OS Concepts: Process scheduling, virtual memory, deadlock, context switching, memory allocation, disk scheduling, and threading/mutex.
• CS Fundamentals: Growth rate charts (Big O Notation) and standard SDLC models (Agile, DevOps, Waterfall).
• Git Visualizer: Run commands (commit, branch, merge, rebase, reset) and watch the commit tree build live.
💻 POWERFUL CODING SANDBOX & TOOLS:
• Interactive Code Editor: Write, edit, and visualize variables, call stack frames, and heap allocations in your own custom Java, Python, C++, or JavaScript code.
• Draggable Visualizer Split & Pinch-to-Zoom layout.
• Scan Code: Instantly import paper/screen code using on-device OCR.
• Complexity Badges: Dynamic Big-O badges and live operation history logs.
💼 CAREER & INTERVIEW PREPARATION:
• Resume Builder: Design print-ready, ATS-friendly developer resumes with professional academic/classic templates.
• Custom Prep Lists: Group topics into trackable checklists to organize your study goals.
🏆 ENGAGEMENT, GAMES & REWARDS:
• CS Mini-Games: Play Refactor Rush (trivia), Scale Fail (on-call incidents), and System Builder (network architecture).
• Quizzes: Shuffled Daily Challenge and Section-based quizzes to earn XP.
• Monthly Leagues: Compete against bots to climb tiers (Wood to Diamond).
🎥 OFFLINE VIDEO RECORDINGS (Pro):
• Record visualization frames with TTS audio narration and Closed Captions (CC) to watch offline anytime.
📱 PREMIUM MOBILE EXPERIENCE:
• 100% Offline Support: Learn on the go, no internet required.
• TTS Voice Narration: Listen to detailed algorithm walkthroughs.
• Vibrant Dark Mode: Beautiful visual themes designed to reduce eye strain.
