About

DSA Master is a learning app for computer science students, software engineers, and anyone preparing for technical interviews. It covers more than 50 data structures and algorithms, with interactive visualizations that show each step as the algorithm runs. A live code playground lets you write, edit, and run code in Python, JavaScript, Java, C++, Kotlin, Dart, and Go, and see the output, errors, and execution time. You can copy or share code examples and work through hands-on practice challenges. It is a practical way to build intuition for algorithms, from arrays and linked lists to graph algorithms.
