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.
