You are given a room of length L and breadth B which is dividen into unit cells. In each unit cell there are some gems which amount to a certain value which can be positive, negative or even zero. You are asked to answer T queries. Each query consists of a number N and you need to collect gems from N unit cells such that the value of N unit cells when summed up must be maximum. The selection of N unit cells in a room of length L and breadth B must be in such a way that it must be a small room of length say some x and breadth some y provided x*y=N.If No such value for x and y exist then print -1.
Input
First line of input contains two space separated integers L and B which denotes the length and breadth of the room.
Following L lines contains B elements in each line each element specifying the value of the gems.
Next line contains T which is the number of queries.
Following T lines contains T elements where each element is the number N.
1<=L,B<=1000
All the L*B elements(x) will be in the range -100<=x<=100
1<=T<=10
1<=N<=10000
Output
Print the maximum value that can be obtained for each value of N.
