Problem Description
Given a string S[0,...n-1],and the length of each palindrome substring in S is less than 20.
Define special string of a palindrome string STR[0,...,n-1] is STR[floor(n/2),...,n-1]
Given L,R and a string T, Query the number of palindrome strings, whose the prefix of special string is T, in S[L,...,R]
ps:floor means the function in C++ language
(No relation between statement and title)
Input
There are severval cases,please peocess until EOF.
The first line contains string S.(1<=|S|<=1e5)
The second line is a number q means the number of querys.(1<=q<=1e5)
The next q lines,each line contains two numbers L,R and a string T.(1<=L<=R<=|S|,1<=|T|<=10)
All strings only contain 'a','b','c','d' and 'e'.
Output
For each query,you should output the number of palindrome strings which satisfied previous condition in a line.
