NUMOFPAL - Number of Palindromes

求一个串中包含几个回文串 感谢@yler 提供翻译

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.

The string S.

The value of function NumPal(s).

malayalam

15

**Limitations** 0 < |s| <= 1000
