The insurance guy laughs, he's just kidding. He just needs an updated list. You just need one of those Rammstein Vodka bottles.

Given an object with alcoholic drinks and a number, return a string with the name of the Rammstein bottle that matches the given number.

Examples

{ whiskey: 100, "Rammstein A": 100, "Rammstein B": 50 } ➞ "Rammstein A"
// number = 100

{ whiskey: 100, "Rammstein A": 100, "Rammstein B": 50 } ➞ "Rammstein B"
// number = 50

{ whiskey: 100, "Rammstein A": 100, "Rammstein D": 70, beer: 70 } ➞ "Rammstein D"
// number = 70

Notes

• There will always be a corresponding Rammstein bottle for the number given.
• There will never be 2 Rammstein bottles with the same number.
• You always return one Rammstein bottle.
