You recently came up with a Start-up Idea - You have contacts with various cab services and you provide your clients the cheapest cab.

There are N cab services. Each has a base fare b[i] and additional cost for every kilometer a[i].

You need to print the minimum cost by wisely choosing appropriate cab service.

Input Format:-
First line of input is a single integer N - number of cab services.
Next N lines consists of 2 space-separated integers b[i] and a[i].
Next line contain an integer Q denoting the number of queries.
Q lines follows - each containing a single integer X - number of kilometers to be travelled.

Output Format:-
Output a single integer per test case denoting the minimum cost by selecting appropriate cab service.

Constraints:-
1 ≤ N,Q\(10^{5}\)
0 ≤ a[i],b[i]\(10^{4}\)
0 ≤ X\(10^{5}\)

SAMPLE INPUT

1 5
10 3
20 2
40 1

SAMPLE OUTPUT

61
Explanation

For first query, First cab service costs 5x4+1 = 21
Second cab service costs 3x4+10 = 22
Third cab service costs 2x4+20 = 28
Fourth cab service costs 1x4+40 = 44

So the minimum cost for first query is 21.
Similarly for other queries.
