Professor GukiZ doesn't accept string as they are. He likes to swap some letters in string to obtain a new one.

GukiZ has strings a, b, and c. He wants to obtain string k by swapping some letters in a, so that k should contain as many non-overlapping substrings equal either to b or c as possible. Substring of string x is a string formed by consecutive segment of characters from x. Two substrings of string x overlap if there is position i in string x occupied by both of them.

GukiZ was disappointed because none of his students managed to solve the problem. Can you help them and find one of possible strings k?

Input Format(From the terminal/stdin)

The first line contains string a, the second line contains string b, and the third line contains string c (1 \le |a|,|b|,|c| \le 105, where |s| denotes the length of string s).

All three strings consist only of lowercase English letters.

It is possible that b and c coincide.

Output Format(To the terminal/stdout)

Find one of possible strings k, as described in the problem statement. If there are multiple possible answers, print any of them.

Hints

In the third sample, this optimal solutions has three non-overlaping substrings equal to either b or c on positions 1—2 (ab), 3—4 (ab), 5—7 (aca). In this sample, there exist many other optimal solutions, one of them would be acaababbcc.
