题目描述
Mirko got a summer internship in a big IT company. This company builds a large database consisting of N rows and M columns.
On his first day, Mirko received a total of Q queries. Each query consists of M numbers.
However, some numbers got lost during transition, so they are denoted with -
1. Mirko wants to know how many rows of the database correspond to the query, i.e., how many rows of the database have identical numbers as the query, excluding -
1.
For example, if the query is in the form of -1 3 2, then we need to count the rows of the database that have any number in the first column, have the number 3 in the second column, and have the number 2 in the third column.
Since he just started with his internship, Mirko needs your help. Help him and answer the queries!

输入格式
The first line of input contains N (1 ≤ N ≤ 10^3) and M (1 ≤ M ≤ 10^3), the size of the database.
Each of the following N lines contains M numbers Aij (1 ≤ Aij ≤ 10^6), the content of the database.
The following line contains Q (1 ≤ Q ≤ 50), the number of queries.
Each of the following Q lines contains M numbers Bij (Bij = -1 or 1 ≤ Bij ≤ 10^6), the description of the i^th query.

输出格式
The output must contain Q lines, each line containing X, the answer to the i^th query from the task.

说明/提示
Clarification of the first example:
The first query asks how many rows have the number 2 in the third column. These are rows number 1 (1
5 2) and number 3 (4 3 2).
The second query asks how many rows have the numbers 3 and 2 in the second and third column. This
is only row number 3 (4 3 2).
The third query asks how many rows are there in total, and the answer is obviously 4.
The first query asks how many rows have the number 2 in the third column. These are rows number 1 (1
