Raindrops is a slightly more complex version of the FizzBuzz challenge, a classic interview question.

Your task is to convert a number into its corresponding raindrop sounds.

If a given number:

• is divisible by 3, add "Pling" to the result.
• is divisible by 5, add "Plang" to the result.
• is divisible by 7, add "Plong" to the result.
• is not divisible by 3, 5, or 7, the result should be the number as a string.

Examples

• 28 is divisible by 7, but not 3 or 5, so the result would be "Plong".
• 30 is divisible by 3 and 5, but not 7, so the result would be "PlingPlang".
• 34 is not divisible by 3, 5, or 7, so the result would be "34".
