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: $S_1$ $S_2$ $S_3$ $T$ [samples]
