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".
