You are given $N$ strings $S_1, S_2, \ldots, S_N$ consisting of lowercase English letters.

Define $N$ digits $C_1, C_2, \ldots, C_N$ as follows:

• If the first character of $S_i$ is one of a, b, c, then $C_i=$ 2
• If the first character of $S_i$ is one of d, e, f, then $C_i=$ 3
• If the first character of $S_i$ is one of g, h, i, then $C_i=$ 4
• If the first character of $S_i$ is one of j, k, l, then $C_i=$ 5
• If the first character of $S_i$ is one of m, n, o, then $C_i=$ 6
• If the first character of $S_i$ is one of p, q, r, s, then $C_i=$ 7
• If the first character of $S_i$ is one of t, u, v, then $C_i=$ 8
• If the first character of $S_i$ is one of w, x, y, z, then $C_i=$ 9

Output the string obtained by concatenating $C_1, C_2, \ldots, C_N$ in this order.

给你 $N$ 个由小写英文字母组成的字符串 $S_1, S_2, \ldots, S_N$。

定义 $N$ 个数字 $C_1, C_2, \ldots, C_N$ 如下：

• 若 $S_i$ 的首字符为 a、b 或 c，则 $C_i = 2$
• 若 $S_i$ 的首字符为 d、e 或 f，则 $C_i = 3$
• 若 $S_i$ 的首字符为 g、h 或 i，则 $C_i = 4$
• 若 $S_i$ 的首字符为 j、k 或 l，则 $C_i = 5$
• 若 $S_i$ 的首字符为 m、n 或 o，则 $C_i = 6$
• 若 $S_i$ 的首字符为 p、q、r 或 s，则 $C_i = 7$
• 若 $S_i$ 的首字符为 t、u 或 v，则 $C_i = 8$
• 若 $S_i$ 的首字符为 w、x、y 或 z，则 $C_i = 9$

请输出将 $C_1, C_2, \ldots, C_N$ 按此顺序拼接后得到的字符串。

The input is given from Standard Input in the following format:

$N$
$S_1$ $S_2$ $\ldots$ $S_N$

输入从标准输入中按以下格式给出：

$N$
$S_1$ $S_2$ $\ldots$ $S_N$

Output the string obtained by concatenating $C_1, C_2, \ldots, C_N$ in this order.

按此顺序连接 $C_1, C_2, \ldots, C_N$ 后得到的字符串。

Sample 1 Explanation:

• The first character of $S_1=$ algorithm is a, so $C_1=$ 2.
• The first character of $S_2=$ heuristic is h, so $C_2=$ 4.

Thus, output 24, which is their concatenation.

Constraints

• $1 \leq N \leq 10$
• $N$ is an integer.
• $S_i$ is a string of length between $1$ and $10$, inclusive, consisting of lowercase English letters.

样例 1 解释：

• $S_1 =$ algorithm 的首字符为 a，因此 $C_1 =$ 2。
• $S_2 =$ heuristic 的首字符为 h，因此 $C_2 =$ 4。

因此，输出其拼接结果 24。

约束条件

• $1 \leq N \leq 10$
• $N$ 是一个整数。
• $S_i$ 是一个长度在 $1$ 到 $10$（含）之间的字符串，仅由小写英文字母组成。
