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 $k$ ?

The first line contains string $a$ , the second line contains string $b$ , and the third line contains string $c$ ( $1<=|a|,|b|,|c|<=10^{5}$ , 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.

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

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 $acaababbcc$ .
