• 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".
