The groups will come to you one after another, and you know for each group the number of rooms it requires. You always assign a group to the first hotel having enough rooms. After this, the number of free rooms in the hotel decreases.
The first input line contains two integers $n$ and $m$: the number of hotels and the number of groups. The hotels are numbered $1,2,\ldots,n$.
The next line contains $n$ integers $h_1,h_2,\ldots,h_n$: the number of free rooms in each hotel.
The last line contains $m$ integers $r_1,r_2,\ldots,r_m$: the number of rooms each group requires.
Print the assigned hotel for each group. If a group cannot be assigned a hotel, print 0 instead.
- $1 \le n,m \le 2 \cdot 10^5$
- $1 \le h_i \le 10^9$
- $1 \le r_i \le 10^9$
