Solving algorithms with reduce
We can solve algorithms with reduce
by following a functional approach. The following lines declare a new getNamesSeparatedBy
method for our previously coded GameRepository
class that solves an algorithm by calling the reduce
method. The code file for the sample is included in the swift_3_oop_chapter_07_31
folder:
open func getNamesSeparatedBy(separator: String) -> String { let gamesNames = getUppercasedNames() return gamesNames.reduce("") { concatenatedGameNames, gameName in print(concatenatedGameNames) let separatorOrEmpty = (gameName == gamesNames.last) ? "" : separator return "\(concatenatedGameNames)\(gameName)\(separatorOrEmpty)" } }
The getNamesSeparatedBy
method receives a separator
argument of the String ...
