# Raindrops Write a program that converts a number to a string, the contents of which depends on the number's factors. - If the number contains 3 as a factor, output 'Pling'. - If the number contains 5 as a factor, output 'Plang'. - If the number contains 7 as a factor, output 'Plong'. - If the number does not contain 3, 5, or 7 as a factor, just pass the number's digits straight through. ## Examples - 28's prime-factorization is 2, 2, 7. - In raindrop-speak, this would be a simple "Plong". - 1755 prime-factorization is 3, 3, 3, 5, 13. - In raindrop-speak, this would be a "PlingPlang". - The prime factors of 34 are 2 and 17. - Raindrop-speak doesn't know what to make of that, so it just goes with the straightforward "34". To run the tests simply run the command `go test` in the exercise directory. If the test suite contains benchmarks, you can run these with the `-bench` flag: go test -bench .
