Problem: Given a string S, count the number of non empty sub strings that are palindromes.
A sub string is any continuous sequence of characters in the string.
A string is said to be palindrome, if the reverse of the string is same as itself.
Two sub strings are different if they occur at different positions in S

Input
Input contains only a single line that contains string S.   

Output
Print a single number, the number of sub strings that are palindromes.

Constraints
1 ≤ |S| ≤ 50
S contains only lower case latin letters, that is characters a to z.

SAMPLE INPUT
dskjkd

SAMPLE OUTPUT
7

Explanation

The 7 sub strings are d, s, k, j, k, d, kjk.

Solution (in PYTHON):

Solution:
def pali(s):
	l=s[::-1]
	if(l==s):
		return True
	else:
		return False
x=raw_input()
c=0
for i in range(1,len(x)):
	for j in range(0,len(x)-i+1):
		if(pali(x[j:j+i])==True):
			c+=1
print c
