You'll be able to see results in few seconds.
Publisher Description
A fun and didactic app to learn computer science algorithms!
See how algorithms are working by watching an animation of their execution. Understand how data is manipulated as it is animated through an intuitive representation of its contents. Always know which line is executed in the pseudo-code, what are the values of the variables.
Need to quickly refresh your memory? Just use the app as a quick reference on the main characteristics of each algorithm!
Main features:
- Execute a single instruction, or undo the previous one
- Run, or rewind the algorithm until you decide to pause the execution
- Adjust the speed of the animation
- Best and worst case input data for sorting algorithms
- Change the input data: size (up to 500), maximum value or data distribution (random, sorted, many duplicates, etc.)
- For data structures, choose the next function to execute, or let a scenario choose for you, so you can see how the data structure evolves.
- Landscape or portrait orientation
This version contains the following algorithms:
Linear Data Structures:
- Linked Lists, including a view on memory
- Queue
- Stack
Sorting algorithms:
- Bubble Sort
- Cocktail Sort
- Gnome Sort
- Insertion Sort
- Quick Sort
- Selection Sort
More algorithms and more features are on the way!
Version History Refactored the execution engine to improve performance. 2026.1 May 20 New linear data structure with Linked Lists! With a view on the memory to see where data is allocated and accessed with pointers. 2023.1 04/28/2023 - Updated for iOS 13 (bug fixes & dark mode)
- Fixed UI layout glitches for iPad Pros with bigger screen resolutions 2020.1 03/18/2020 Bug fixes:
- Fixed a bug with 'while' loops and undo, where the first iteration was not undone;
- Fixed a UI bug where undoing an assignment to a variable moved the value from the wrong place;
- Fixed a random crash occurring when 'Done' was tapped while an animation was running;
- Fixed a random crash while animating Queues or Stacks with high speed and auto-generation of the next method to execute; 2018.1 12/18/2018 Linear Data Structures, with:
- Queue (array implementation)
- Stack (array implementation)
- Choose which function to execute next on a data structure, or
- Run a scenario that automatically chooses what function to execute.
- choose the size of the data structure (up to 500 elements) and pre-fill amount.
Bug fixes:
- fixed rare crash with sending mail in portrait. 2017.1 03/20/2017 New features!
- 2 new sorting algorithms: Gnome and Cocktail sort.
- Algorithms can animate even faster. Now you need only a bit of patience for Bubble sort and 500 values.
Fixes:
- support for iOS9 (fixed crashes)
- Comparator now shows the correct index at the bottom. 1.1.0 11/04/2015 Hotfix for iOS 8 compatibility. 1.0.2 10/06/2014 * iOS 7 support
* calculation of the total number of steps happens now in the background to avoid blocking the user interface.
* fixed a bug in the FOR instruction which caused the Insertion Sort to not undo properly. 1.0.1 01/24/2014 1.0 06/18/2013
