### Problem Statement

You are given three strings $S_1, S_2, S_3$ consisting of lowercase English letters, and a string $T$ consisting of 1, 2, 3.

Concatenate the three strings according to the characters in $T$ and print the resulting string. Formally, conform to the following instructions.

• For each integer $i$ such that $1 \leq i \leq |T|$, let the string $s_i$ be defined as follows:
• $S_1$, if the $i$-th character of $T$ is 1;
• $S_2$, if the $i$-th character of $T$ is 2;
• $S_3$, if the $i$-th character of $T$ is 3.
• Concatenate the strings $s_1, s_2, \dots, s_{|T|}$ in this order and print the resulting string.

### Constraints

• $1 \leq |S_1|, |S_2|, |S_3| \leq 10$
• $1 \leq |T| \leq 1000$
• $S_1$, $S_2$, and $S_3$ consist of lowercase English letters.
• $T$ consists of 1, 2, and 3.

### Input

Input is given from Standard Input in the following format:

$S_1$
$S_2$
$S_3$
$T$
