    count

    The count of numbers to generate to the array, randomly.

  • Prepare an array from a specified range sequentially.

    Declaration

    Swift

    mutating func prepare(range: ClosedRange<Int>)

    Parameters

    range

    The range of values the array is holding, e.g. -10..-10.

    mutating func handleSortOperation(operation: SwappedItems)

    Parameters

    Declaration

    Swift

    func containsSameElements(as other: [Element]) -> Bool
