Package for this problem was not updated by the problem writer or Codeforces administration after we’ve upgraded the judging servers. To adjust the time limit constraint, solution execution time will be multiplied by 2. For example, if your solution works for 400 ms on judging servers, then value 800 ms will be displayed and used to determine the verdict.

standard outputLong ago, when Petya was a schoolboy, he was very much interested in the Petr# language grammar. During one lesson Petya got interested in the following question: how many different continuous substrings starting with the *s*_{begin} and ending with the *s*_{end} (it is possible *s*_{begin} = *s*_{end}), the given string *t* has. Substrings are different if and only if their contents aren't equal, their positions of occurence don't matter. Petya wasn't quite good at math, that's why he couldn't count this number. Help him!

Input

The input file consists of three lines. The first line contains string *t*. The second and the third lines contain the *s*_{begin} and *s*_{end} identificators, correspondingly. All three lines are non-empty strings consisting of lowercase Latin letters. The length of each string doesn't exceed 2000 characters.

Output

Output the only number — the amount of different substrings of *t* that start with *s*_{begin} and end with *s*_{end}.

In the third sample there are four appropriate different substrings. They are: ab, abab, ababab, abababab.

In the fourth sample identificators intersect.
