/* a function called sumOfDigits that given an integer, returns the sum of its digits. If you need an extra challenge, find a solution that works without using Strings.

Example

sumOfDigits(23) // returns 5
sumOfDigits(496) // returns 19

 Thoughts: This does not work with one digit because I don't have anything to add it to
 example:
 sumofDigits(5) // Error

 Process: I need to pass an integer through and the expand it into single digits and then add the digits together and return the sum

 I know we can do something like thsi but that passes in a string not an int.

 let number = "1256"

 let array = number.characters.flatMap{Int(String($0))} /

func sumOfDigits(number: Int) -> Int {

    return int
