Challenge task 1 of 1
Given the isDivisible function, create another function called isNotDivisible which also takes in two parameters, namely the dividend and the divisor. It should also return a Bool. The goal of this new function is to let you know whether a dividend is NOT divisible by the divisor. (Note: the function should return only a Bool and not an optional.)
Bummer! You need to define a func named isNotDivisible that takes a Int parameter named dividend and another Int parameter named divisor and returns a Bool.
func isNotDivisible(#dividend: Int, #divisor: Int) -> Bool? {
if dividend % divisor == 0 {
return true
}
return nil
}
if let divisible = isNotDivisible(dividend: 2, divisor: 8) {
println("Divisible")
} else {
println("Is not divisible")
}

14,957 Pointsit should look something like this:
func isNotDivisible (#dividend: Int, #divisor: Int) -> Bool {
if dividend % divisor != 0 {
return true
} else {
return false
}
}
