Hi, here’s your problem today. This problem was recently asked by Microsoft:

Given a string, determine if there is a way to arrange the string such that the string is a palindrome. If such arrangement exists, return a palindrome (There could be many arrangements). Otherwise return None.

Here’s some starter code:

```
def find_palindrome(s):
# Fill this in.
print(find_palindrome('momom'))
# momom
```
