NUMOFPAL - Number of Palindromes

Each palindrome can be always created from the other palindromes, if a single character is also a palindrome. For example, the string "malayalam" can be created by some ways:

  • malayalam = m + ala + y + ala + m
  • malayalam = m + a + l + aya + l + a + m

We want to take the value of function NumPal(s) which is the number of different palindromes that can be created using the string S by the above method. If the same palindrome occurs more than once then all of them should be counted separately.

Input

The string S.

Output

The value of function NumPal(s).

Limitations

0 < |s| <= 1000

Example

Input:
malayalam

Output:
15

So problem can be formulated in another way:
How many palindromic substrings does this string contain?
For test input 2 substrings S[1,3] = "ala" and S[5,7]="ala" are different.

Just outputs the number of palindromic substrings of the input string. (If the same palindrome occurs more than once then all of them should be counted separately.)
