P8838 [ChuanZhi Cup #3 Finals] Interview.

disangan233 and disangan333 went to an interview. The interviewer gave them a problem. Can you, as a helpful person, assist them?

There are $n$ servers. Server $i$ can process data of size at most $a_i$. Next, there will be $k$ commands $b_k$. Command $i$ means sending data of size $b_i$, and you need to assign an idle server to it. Please compute a sequence $p_k$ indicating that the data of command $i$ is assigned to server $p_i$, and $p_k$ is lexicographically smallest. If it is impossible to assign, output "-1". For all testdata, $n, k \leq 6$, $a_i, b_i \leq 10$.

The input consists of $3$ lines. Line $1$ contains two positive integers $n, k$. Line $2$ contains $n$ positive integers $a_i$, where $a_i$ indicates the maximum data size that server $i$ can process. Line $3$ contains $k$ positive integers $b_i$, where $b_i$ indicates command $i$.

Output one line containing $k$ positive integers $p_1 \ldots p_k$, or output "-1".

### Sample Explanation Command $1$ is assigned to server $1$. Command $2$ is assigned to server $3$. Command $3$ is assigned to server $2$. Command $4$ is assigned to server $4$. Command $5$ is assigned to server $6$. Command $6$ is assigned to server $5$. Translated by ChatGPT 5
