Usage

There are two ways you can test the solutions found in here.

1. Terminal

The first one is the most obvious one, simply compile and run from terminal using single command

$ xcrun swift challenge-solution.swift    

where 'challenge-solution.swift' is any swift source file from this repository. This will be the best way to quickly test the solution with console input.

2. Xcode Playground

The second option is to copy code from the source file and paste it into the Xcode Playground. Nearly all of the solutions that you can find here need some kind of input, so don't be surprised when Playground will give you an error. You will need to remove any call to 'readLine()' and hardcode any desired input.

Note
