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`

.

- $S_1$, if the $i$-th character of $T$ is
- Concatenate the strings $s_1, s_2, \dots, s_{|T|}$ in this order and print the resulting string.

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

,`2`

, and`3`

.

Input is given from Standard Input in the following format:

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

Print the answer.

We have $s_1 = $ `mari`

, $s_2 = $ `zzo`

, $s_3 = $ `to`

, $s_4 = $ `mari`

. Concatenate these and print the resulting string: `marizzotomari`
