#Here is code to count of Palindromic Strings possible by swapping of a pair of Characters and the other steps required.
 def findNewString ( s ) :
	ans = 0
	freq = [ 0 ] * 26
	n = len ( s )
	for i in range ( n ) :
		ans += freq [ ord ( s [ i ] ) - ord ( ' a ' ) ]
		freq [ ord ( s [ i ] ) - ord ( ' a ' ) ] += 1
	return ans
s = " aaabaaa "
print ( findNewString ( s ) )
