# Raindrops

Convert a number to a string, the contents of which depend on the number's factors.

- If the number has 3 as a factor, output 'Pling'.
- If the number has 5 as a factor, output 'Plang'.
- If the number has 7 as a factor, output 'Plong'.
- If the number does not have 3, 5, or 7 as a factor, just pass the number's digits straight through.

## Examples

- 28's factors are 1, 2, 4,
**7**, 14, 28.- In raindrop-speak, this would be a simple "Plong".

- 30's factors are 1, 2,
**3**,**5**, 6, 10, 15, 30.- In raindrop-speak, this would be a "PlingPlang".

- 34 has four factors: 1, 2, 17, and 34.
- In raindrop-speak, this would be "34".

## Hints

- Think of this in a generic way. If you're familiar with the (fizz buzz)[https://en.wikipedia.org/wiki/Fizz_buzz] problem this is similar except there are three conditions instead of two. How would you implement this knowing that one day we might want to extend to four, five, or even ten types of raindrops? ## Source
