# 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". * * * * For installation and learning resources, refer to the [exercism Racket page](http://exercism.io/languages/racket).
