Alphabet Soup

Create a function that takes a string and returns a string with its letters in alphabetical order.

Examples

AlphabetSoup("hello") ➞ "ehllo"

AlphabetSoup("daiebt") ➞ "abdeit"

AlphabetSoup("hacker") ➞ "acehkr"

AlphabetSoup("geek") ➞ "eegk"

AlphabetSoup("javascript") ➞ "aacijprstv"

Notes

You can assume numbers and punctuation symbols won't be included in test cases. You'll only have to deal with single word, alphabetic characters.
