# Raindrops
|
||
|
|
|
||
|
|
Write a program that converts a number to a string, the contents of which depends on the number's prime factors.
|
||
|
|
|
||
|
|
- If the number contains 3 as a prime factor, output 'Pling'.
|
||
|
|
- If the number contains 5 as a prime factor, output 'Plang'.
|
||
|
|
- If the number contains 7 as a prime factor, output 'Plong'.
|
||
|
|
- If the number does not contain 3, 5, or 7 as a prime 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 .
|
||
|
|
|
||
|
