NSUBSTR2 - Substrings II
You are given a string T which consists of 40000 lowercase latin letters at most. You are also given some integers A, B and Q. You have to answer Q queries. For i-th query you are given a string Si and you need to output how many times Si appears in T. Immediately after answering the current query you need to add ((A*ans+B) modulo 26+1)-th lowercase symbol of the English alphabet to the end of T where ans is the answer to this query.
Input
The first line of input contains a string T. The next line consists of three integers Q (1<=Q<=40000), A (0<=A<=27) and B (0<=B<=26). The following Q lines contain Q query strings, Si-2 on i-th line. Input will not exceed 600 kb.
Output
Output Q lines. Output the answer to the i-th query on the i-th line output.
Example
Input:
aaaaa
2 0 0
a
aa
Output:
5
5

@ ljmocic: As Encho previously said, SPOJ always tests on *all* testcases, then reports the *first* error it found while doing so. As such, it might not be the 14th that's causing your SEGF, it could be any of them.

What is wrong with 14th test case? Always getting segmentation fault on that case. |

As far as I know SPOJ doesn't stop grading once you get WA or TL, therefore all these comments "What is test #14, i get WA" are useless. I think there are 14 tests in total, if you're getting WA - then one of them is wrong, not necessarily the 14th. |

A and B should not be 0 according to the Input section, but they are 0 in the example.
