About this app

Master Data Structures and Algorithms (DSA) with Ease:
Whether you're just starting or an experienced coder, our app offers step-by-step tutorials that break down complex concepts into bite-sized lessons. Each chapter is designed to be beginner-friendly, featuring clear explanations, practical examples, and helpful visuals to ensure you grasp every topic effortlessly.

Learn DSA in Your Preferred Language:
Master DSA concepts in C, Java, Python, or JavaScript with our easy-to-follow tutorials. Whether you're coding in one language or learning multiple, our app makes understanding data structures and algorithms (DSA) effortless across all these languages.

Bring DSA to Life with GIFs and Real-Time Algorithm Visualization:
Make learning Data Structures and Algorithms (DSA) more engaging with GIFs that break down complex ideas. Visualize key concepts in action and watch them come to life for easier understanding. Plus, dive deeper with the Algorithms Visualizer, offering a hands-on, real-time experience to see how algorithms process data, making learning interactive and effortless.

Ace Your Interviews with Real Questions and Code Solutions:
Prepare for top company interviews with popular questions and solutions, featuring code examples in C, JavaScript, Python, and Java. Get insights from Google, Amazon, Oracle, and Microsoft interviews, all in one app. Plus, find topics fast with the built-in search and copy code snippets with just one tap.

New: Step-by-Step Visualizers with Live Code Sync:
Watch algorithms run one step at a time with play, pause, step, and rewind controls. The pseudocode line being executed lights up in sync with every animation, so you read the algorithm as it runs. See Bubble Sort swap elements, AVL and Red-Black Trees rebalance, and Bellman-Ford relax edges. Includes sorting, searching, stacks, queues, linked lists, tree traversals, BFS/DFS, Prim's and Kruskal's MST. You can even type your own numbers and run sorting or search on your own data.

New: Practice Smarter:
Try the Code Playground to write and run code inside the app. Take mock interviews with scoring and weak-topic analytics. Revise fast with flashcards and daily challenges. Practice problems are now tagged by company, topic, and difficulty (Easy, Medium, Hard). Earn XP, badges, and streaks as you learn. And everything works fully offline.

Ratings and reviews

It will be better if you add the next option within the chapter as its annoying to move back and get in the next chapter subsequently. But honestly its the best ever app of DSA notes with providing coding area for practicing and a very user friendly interface. I will must say "Try it once".

Just waste. I have purchased Pro, but it's useless. The app won't work properly. Exampl: in linear or binary search it wont ahow complexity under that tab. Instead it shows some different. Feeling wasted the money on this useless.

This app is an excellent app which helps me a lot to learn dsa. I have only one problem with this app that.... The codes are in only C language but I'm a C++ programmer. If we could get all the codes in C++.... That will be helpful for me or many others.
