Palindrome
Problem
At the input of the program are uppercase Latin letters, the input of these characters ends with a dot. Write a time and memory efficient program that will determine whether these letters can be rearranged to form a palindrome (a palindrome reads the same from left to right and from right to left). The program should output the answer "Yes" or "No", and in the case of the answer "Yes", – also the resulting palindrome itself (first in alphabetical order).
Input string example:
GANN.
Sample output:

ANGNA
