Sorting Algorithms App

An open source app focused on show in a visual way how sorting algorithms actually works.

• Unit Tests
• More features on backlog :)

Adding a new algorithm

Create a class implemeting the protocol Algorithm. Following the example for the class InsertionSort, you'd need to set the title of your algorithm, the image (pick a nice logo representing your algorithm:)) and description. In the method GenerateSwaps, add the necessary logic to generate all cell swaps which would be necessary.

final class InsertionSort: Algorithm {
    
    final var title: String = "Insertion Sort"
    final var image: String = "ic_insertion"
    final var description: String = "Insertion Sort Description"
    
    final func generateSwaps(from list: [Int]) -> [(x0: Int, x1: Int)] {
        if list.count == 1 { return [] }
        
        var array = list
        var swaps = [(x0: Int, x1: Int)]()
        
        // APPEND ALL GENERATED SWAPS TO IT'S ARRAY
        
        return swaps
    }
}

Update the data source with your new algorithm

class AlgorithmsListPresenter {
    
    private weak var view: AlgorithmsListView?
    private let router: AlgorithmsListRoutering
    
    private let dataSource: [Algorithm] = [
        BubbleSort(),
        InsertionSort(),
        SelectionSort()
    ]
 ...
}
