A13789. Lucky Numbers (Easy Version)

This is the easy version of the problem. The only difference is that in this version $q=1$ . You can make hacks only if all versions of the problem are solved.

Zookeeper has been teaching his $q$ sheep how to write and how to add. The $i$ -th sheep has to write exactly $k$ non-negative integers with the sum $n_i$ .

Strangely, sheep have superstitions about digits and believe that the digits $3$ , $6$ , and $9$ are lucky. To them, the fortune of a number depends on the decimal representation of the number; the fortune of a number is equal to the sum of fortunes of its digits, and the fortune of a digit depends on its value and position and can be described by the following table. For example, the number $319$ has fortune $F_{2} + 3F_{0}$ .

Each sheep wants to maximize the sum of fortune among all its $k$ written integers. Can you help them?

The first line contains a single integer $k$ ( $1 \leq k \leq 999999$ ): the number of numbers each sheep has to write.

The next line contains six integers $F_0$ , $F_1$ , $F_2$ , $F_3$ , $F_4$ , $F_5$ ( $1 \leq F_i \leq 10^9$ ): the fortune assigned to each digit.

The next line contains a single integer $q$ ( $q = 1$ ): the number of sheep.

Each of the next $q$ lines contains a single integer $n_i$ ( $1 \leq n_i \leq 999999$ ): the sum of numbers that $i$ -th sheep has to write. In this version, there is only one line.

Print $q$ lines, where the $i$ -th line contains the maximum sum of fortune of all numbers of the $i$ -th sheep. In this version, you should print only one line.

In the first test case, $57 = 9 + 9 + 39$ . The three $9$ 's contribute $1 \cdot 3$ and $3$ at the tens position contributes $2 \cdot 1$ . Hence the sum of fortune is $11$ .

In the second test case, $63 = 35 + 19 + 9$ . The sum of fortune is $8$ .
