Given a string s$,$ print "Yes" if the string can be a palindrome after rearranging the letters in the

String, else $"$No$".$ Ignore the case.

A palindromic string is one that reads the same forwards and backwards, such as "radar" or

"level."

Input format

First line contains a string $\text{'}$s$\text{'}$ consisting of uppercase and lowercase letters.

Output format

Print "Yes" if the string can be a palindrome after rearranging the letters in the string,

otherwise, print $"$No$".$

Sample Input $1$

aAb

Sample Output $1$

Yes

Explanation

Swapping $\text{'}$A$\text{'}$ and $\text{'}$b$\text{'}$ in the string will result in a palindromic string 'abA' $(\text{'}$a$\text{'}=\text{'}$A$\text{'}$ as we are

ignoring the case$).$

Sample Input $2$

ABC

Sample Output $2$

No

Explanation

"ABC" cannot be converted into a palindromic string.

Constraints

$1$ s$.$length $1000$
