Problem

you have a string S and two integers p and q and made a rule that names of the babies should be a substring of S, and the length should be between p and q (inclusive).

Now you are given S, p and q you have to find the number of distinct names that can be made.

Input :

The length of S will be between 2 and 10000 (inclusive) and S contains lowercase English letters only. The next line contains two integer p and q (1 ≤ p ≤ q ≤ length(S)).

output :

For each case, print the case number and the number of distinct names that can be made.

Sample :

input:

1

abcdef

2 5

answer:

Case 1: 14

I'm new with Suffix array, i already solve DISUBSTR. and here is my code.

i'm asking how i can modified my code to get the above problem AC ?
