Algorithms HQ v2017.1
A fun and didactic app to learn computer science algorithms!
Support, feedback, feature / algorithms requests: support (at) algorithmshq.com
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!
- 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:
- Bubble Sort
- Cocktail Sort
- Gnome Sort
- Insertion Sort
- Quick Sort
- Selection Sort
Version 2017.1 (Mar. 2017)
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.
- fixed rare crash with sending mail in portrait.
Version 1.1.0 (Nov. 2015)
- 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.
- support for iOS9 (fixed crashes)
- Comparator now shows the correct index at the bottom.
Version 1.0.2 (Oct. 2014)
- Hotfix for iOS 8 compatibility
Version 1.0.1 (Jan. 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.
