Finding the no of permutations of a string that are palindromes

Правка en1, от vee_sharp, 2016-02-13 10:37:26

I am trying to find out the the no of permutations possible for a string that are palindrome.The only way I could think of is finding out the possible permutations and then checking if each one of them is palindrome or not. Is there any better way?
