Problem type

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!

Input Specification

The first line of input contains N (1 \le N \le 10^3) and M (1 \le M \le 10^3), the size of the database.

Each of the following N lines contains M numbers A_{ij} (1 \le A_{ij} \le 10^6), the content of the database.

The following line contains Q (1 \le Q \le 50), the number of queries.

Each of the following Q lines contains M numbers B_{ij} (B_{ij} = -1 or 1 \le B_{ij} \le 10^6), the description of the i^\text{th} query.

Output Specification

The output must contain Q lines, each line containing X, the answer to the i^\text{th} query from the task.

Explanation of Sample Output 1

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.
