| ||A palindrome is a string that is the same whether it is read from left to right or from right to left. Little Dazdraperma likes
palindromes a lot. As a birthday gift she received two strings A and B. Now she is curious if there is a
way to insert string B into string A so that the resulting string is a palindrome. You agreed to help her and
even tell how many different variants of such insertions exist. Two variants are considered different if
string B is inserted in different places. Return the number of possible insertion variants.
For example, let A="aba" and B="b". You can insert B in 4 different places:
So, the answer for this example is 2.
- Before the first letter of A. The result is "baba" and it is not a palindrome.
- After the first letter 'a'. The result is "abba" and it is a palindrome.
- After the letter 'b'. The result is "abba" and it is also a palindrome.
- After the second letter 'a'. The result is "abab" and it is not a palindrome.
|Method signature:||int count(String A, String B)|
|(be sure your method is public)|
|-||A and B will each contain between 1 and 50 characters, inclusive.|
|-||Each character of A and B will be a lowercase letter ('a'-'z').|
|The example from the problem statement.|
|Here every possible insertion point gives you a palindrome.|
