Mastermind is a bright student of his class. To judge his intellegence and speed his teacher has given him a question and he needs your help for solving it. The question is :
Given a sequence of N elements, find all subsequences of this sequence, then compute sum of all these subsequences individually, finally, find the number of subsequences which give minimum XOR with a given value A. He can solve this question very quickly but now he needs your help as the number of such questions is very large.
INPUT
First line of the input contains a single integer N denoting the number of elements in the sequence. Next line of the input contains N space separated integers. Next line of the input contains a single integer Q denoting the number of queries. Next Q lines of input contains a single integer denoting the value of A.
OUTPUT:
Output consists of Q lines each containing two integers. First integer denotes the sum of the elements in the chosen subsequence and second integer denotes the number of such subsequences.
NOTE
Since the number of such subsequences can be very large print the second integer modulo 10^9+7.
CONSTRAINTS
1<=N<=100
1<=value of elements in the sequences<=1000
Q<=5*10^5
1<=A<=10^9
Lets form all the possible subsets
{1} , -> sum 1 {2}, -> sum 2 {3}, -> sum 3 {1,2}, -> sum 3 {1,3}, -> sum 4 {2,3}, -> sum 5 {1,2,3} -> sum 6
Q1 3
3 can give minimum xor with the sets having sum 3. as there are two sets having sum 3. ans: 3 2
Q2 5
5 can give minimum xor with the sets having sum 5. as there are 1 set having sum 5. ans: 5 1
Q3 7
7 can give minimum xor with the sets having sum 6. as there are 1 set having sum 6. ans: 6 1
