I'm doing this problem set "FizzBuzz", and my switch statement is giving me some problems, here's my code:
func fizzBuzz(n: Int) -> String {
switch n {
case n % 3 == 0: print("Fizz")
case n % 5 == 0: print("Buzz")
case n % 15 == 0:print("FizzBuzz")
}
return "\(n)"
}
If you could provide me with pointers / hints, instead of giving me the correct code, that would be swell :D I'd prefer solving it myself, but a few hints could get me out of this hole.
You can use case let
where
and check if both match before checking them individually:
func fizzBuzz(n: Int) -> String {
let result: String
switch n {
case let n where n.isMultiple(of: 3) && n.isMultiple(of: 5):
result = "FizzBuzz"
case let n where n.isMultiple(of: 3):
result = "Fizz"
case let n where n.isMultiple(of: 5):
result = "Buzz"
default:
result = "none"
}
print("n:", n, "result:", result)
return result
}
