题目描述
After a long day and miserable at work, Mirko decided to order a pizza for dinner to cheer himself up. In a big pile of papers on his desk, he found a flyer of a nearby pizza restarant.
The restarant offers m different pizzas. Pizza toppings are labeled with positive integers.
i-th pizza has ki toppings, with labels bi,1, bi,2, . . . , bi,ki .
Mirko is very picky when it comes to food. He doesn’t like n toppings, those with labels a1, a2, . . . , an, so he wants to order a pizza that doesn’t contain any of those toppings. Determine the number of pizzas that Mirko can order.
输入格式
The first line contains an integer n (1 ≤ n ≤ 100), the number of toppings, followed by n distinct integers ai (1 ≤ ai ≤ 100), the labels of toppings Mirko dislikes.
The second line contains an integer m (1 ≤ m ≤ 100), the number of pizzas.
The following m lines describe the pizzas. The i-th line contains an integer ki (1 ≤ ki ≤ 100), the numer of toppings, followed by ki distinct integers bi,j (1 ≤ bi,j ≤ 100), the labels of toppings on the i-th pizza.
The pizzas, i.e. the sets of toppings, will be distinct.
