About this app
DSAlgo is the ultimate visual learning companion for computer science, coding interviews, and software engineering. Visualize data structures, algorithms, AI/ML, system design, and real-world architectures with step-by-step animations, code tracing, and voice narration.
Struggling to understand complex algorithms? DSAlgo brings every concept to life - perfect for FAANG prep, university exams, or self-improvement!
🔍 WHAT YOU GET:
📦 Data Structures (23 types, 200+ operations):
Arrays, Linked Lists, Doubly Linked Lists, Stack, Queue, Deque, Hash Table, Binary Tree, BST, AVL Tree, Red-Black Tree, Max/Min Heap, Priority Queue, Trie, Segment Tree, Fenwick Tree, Graph, Disjoint Set, Suffix Array, Bloom Filter, LRU Cache, LFU Cache. Watch every pointer, node, and edge animate live with narration.
⚡ Algorithms (22+ categories, 126 algorithms):
Sorting (15: Merge, Quick, Heap, Radix, Counting...), Searching, Two Pointers, Sliding Window, Recursion and Memoization, Backtracking (N-Queens, subsets, permutations), Divide and Conquer, Dynamic Programming (35 problems: Knapsack, LCS, LIS, Edit Distance, Coin Change...), Greedy, String Matching (KMP, Rabin-Karp, Z-algorithm), Bit Manipulation, Number Theory, Matrix, Intervals, Binary Search Variants, Prefix Sum, Geometry, Compression, Combinatorics, Randomized, Order Statistics, and Game Theory / Minimax.
🧠 AI and Machine Learning (50+ topics):
• LLM Architecture: Tokenization, embeddings, attention, transformer blocks, KV cache, RoPE, quantization, MoE, RAG, and AI agent loops.
• Machine Learning: Supervised (Regression, Decision Trees, SVM, XGBoost, k-NN), Unsupervised (K-Means, DBSCAN), Deep Learning (ANN, CNN, RNN, LSTM), Reinforcement Learning (Q-Learning, DQN, Policy Gradient), and PCA / t-SNE.
🖥️ CS Fundamentals (8 sections):
OS (scheduling, virtual memory, deadlock, mutex, inode), Networking (TCP, DNS, HTTP, TLS, NAT, ARP), DBMS (SQL, B-Tree, ACID, WAL, replication, connection pooling), Big O Notation, Compiler Design (Lexer to Code Gen), Cryptography (SHA-256, AES, RSA, JWT, TLS), SDLC (Agile, DevOps, Waterfall), and Raft and Paxos distributed consensus.
🏗️ System Design (70+ topics):
High Level Design (URL Shortener, Twitter, Netflix, Uber, Rate Limiter, 18+ more), Low Level Design, and all 21 Gang of Four Design Patterns with animated UML diagrams.
🌐 Real-World Systems (100 flows):
Step-by-step animated architecture flows of real systems: ChatGPT inference, Google Search, Snapchat stories, Netflix CDN, Instagram feed, Uber dispatch, YouTube streaming, WhatsApp messaging, Airbnb booking, and 91+ more.
💻 Programming Languages (4 languages, Java, Python, C++, Golang):
OOP, collections, concurrency, memory management, generics, streams, error handling, goroutines, STL, and design principles - visualized step by step.
🔀 Git Visualizer: Type commands and watch commits, branches, merges, rebases, and resets animate live on a dynamic commit tree.
🛠️ DevOps: Docker container lifecycle, image layer builds, Docker Compose, Kubernetes pod scheduling, rolling updates, and service load balancing.
💡 Code Challenge Solver:
Solve coding challenges in Python, Java, C++, and JavaScript with an interactive code editor, smart autocompletion, syntax highlighting, and instant test case results with pass/fail breakdown.
💼 CAREER AND INTERVIEW PREP:
• Resume Builder: ATS-friendly developer resumes with professional templates.
• Custom Prep Lists: Trackable checklists to organize your interview study plan.
🏆 GAMES AND REWARDS:
Refactor Rush (trivia), Scale Fail (on-call incidents), System Builder (network game), Daily Quizzes, XP system, and Monthly Leagues from Wood to Diamond.
🎥 OFFLINE VIDEO RECORDINGS (Pro): Record visualizations with TTS narration and Closed Captions to watch offline anytime.
📱 100% Offline, TTS Voice Narration, Vibrant Dark Mode.
