php-raindrops's Introduction
- 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.
- 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".
