Unlock the world of algorithms with Algorithm++! Visualize, listen, and master the logic behind sorting algorithms. Whether you are a Computer Science student preparing for exams, a developer brushing up for technical interviews, or an enthusiast who enjoys satisfying visualizations, Algorithm++ is the ultimate educational tool. Visualize & Customize Watch 16 different sorting algorithms in action. Use the dynamic sliders to adjust the sorting speed and change the array size from 10 to 100 items. Experience the difference between O(n²) and O(n log n) visually. Hear the Algorithms (Sonification) Don't just watch—listen! Algorithm++ features a real-time audio oscillator that generates sound based on value comparisons and swaps. Hear the chaotic noise of a random array transform into a satisfying, rising scale as it gets sorted. Inspect the Code Learn how it works under the hood. View the actual Swift source code for every algorithm with beautiful syntax highlighting. Perfect for understanding the implementation details. Master Big O Complexity Get instant access to Time Complexity and Space Complexity data for every algorithm. Understand the efficiency trade-offs between different methods. Test with Real-World Patterns Algorithms behave differently based on input data. Use the "Data Patterns" feature to test sorting on: Random: The standard chaos. Sorted: See how algorithms handle already-sorted data. Reversed: The worst-case scenario for many algorithms. Almost Sorted: Watch Insertion Sort shine! Few Unique: Visualize sorting with repeated values. Included Algorithms: From the basics to the advanced, and even the "joke" sorts: Basic: Bubble, Selection, Insertion Efficient: Quick Sort, Merge Sort, Heap Sort, Shell Sort Educational: Cocktail Shaker, Comb, Odd-Even, Gnome, Cycle, Pancake, Stooge Non-Comparative: Radix Sort (LSD) Bonus: Bogo Sort (Good luck!) Features: Clean, modern SwiftUI interface. Interactive controls (Pause, Resume, Step). Mute/Unmute functionality. Detailed algorithm information cards. Dark Mode support. Download Algorithm++ today and turn abstract concepts into clear, interactive experiences!
