题目描述

Bessie is leading the cows in an attempt to escape! To do this, the cows are sending secret binary messages to each other.
Ever the clever counterspy, Farmer John has intercepted the first bi (1 <= bi <= 10,000) bits of each of M (1 <= M <= 50,000) of these secret binary messages.
He has compiled a list of N (1 <= N <= 50,000) partial codewords that he thinks the cows are using. Sadly, he only knows the first cj (1 <= cj <= 10,000) bits of codeword j.
For each codeword j, he wants to know how many of the intercepted messages match that codeword (i.e., for codeword j, how many times does a message and the codeword have the same initial bits). Your job is to compute this number.
The total number of bits in the input (i.e., the sum of the bi and the cj) will not exceed 500,000.
POINTS: 270

输入描述:

* Line 1: Two integers: M and N
* Lines 2..M+1: Line i+1 describes intercepted code i with an integer bi followed by bi space-separated 0's and 1's
* Lines M+2..M+N+1: Line M+j+1 describes codeword j with an integer cj followed by cj space-separated 0's and 1's

输出描述:

* Lines 1..M: Line j: The number of messages that the jth codeword could match.

说明

Four messages; five codewords.
The intercepted messages start with 010, 1, 100, and 110.
The possible codewords start with 0, 1, 01, 01001, and 11.
0 matches only 010: 1 match
1 matches 1, 100, and 110: 3 matches
01 matches only 010: 1 match
01001 matches 010: 1 match
11 matches 1 and 110: 2 matches
