```
Sort by the Letters
Write a function that sorts each string in a list by the letter in alphabetic ascending order (a-z).

Examples
sort_by_letter(["932c", "832u32", "2344b"])
output = ["2344b", "932c", "832u32"]

sort_by_letter(["99a", "78b", "c2345", "11d"])
output = ["99a", "78b", "c2345", "11d"]

sort_by_letter(["572z", "5y5", "304q2"])
output = ["304q2", "5y5", "572z"]

sort_by_letter([])
output = []

#here's your starting point :)
def sort_by_letter(arr):

Notes
- Each string will only have one (lowercase) letter.
- If given an empty list, return an empty list.
```
