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 outputIn mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.

You are given two strings *s*_{1}, *s*_{2} and another string called *virus*. Your task is to find the longest common subsequence of *s*_{1} and *s*_{2}, such that it doesn't contain *virus* as a substring.

Input

The input contains three strings in three separate lines: *s*_{1}, *s*_{2} and *virus* (1 ≤ |*s*_{1}|, |*s*_{2}|, |*virus*| ≤ 100). Each string consists only of uppercase English letters.

Output

Output the longest common subsequence of *s*_{1} and *s*_{2} without *virus* as a substring. If there are multiple answers, any of them will be accepted.

If there is no valid common subsequence, output 0.
