HDU 3294 Girls' research（Manacher算法求回文串左右端点）

One day, sailormoon girls are so delighted that they intend to research about palindromic strings. Operation contains two steps: 
First step: girls will write a long string (only contains lower case) on the paper. For example, "abcde", but 'a' inside is not the real 'a', that means if we define the 'b' is the real 'a', then we can infer that 'c' is the real 'b', 'd' is the real 'c' ……, 'a' is the real 'z'. According to this, string "abcde" changes to "bcdef".
Second step: girls will find out the longest palindromic string in the given string, the length of palindromic string must be equal or more than 2.

InputInput contains multiple cases. 
Each case contains two parts, a character and a string, they are separated by one space, the character representing the real 'a' is and the length of the string will not exceed 200000.All input must be lowercase. 
If the length of string is len, it is marked from 0 to len-1. OutputPlease execute the operation following the two steps. 
If you find one, output the start position and end position of palindromic string in a line, next line output the real palindromic string, or output "No solution!". 
If there are several answers available, please choose the string which first appears. Sample Input

b babd
a abcd

Sample Output

0 2
aza
No solution!

题解：

题意：

先给你一个字符，代表该字符表示‘a’，然后其他25个字符根据该字符来推算，然后给你一个串，让你求出最长回文串的左右端点，如果相等长输出找到的第一个串，并输出根据要求改变后的回文串

思路：

manacher里面稍加修改就行了，就是他一开始输入的字符处理起来有点麻烦。。推算一下就好了
