# Prerequisites?

Freddie the frosh has chosen to take $k$ courses. To meet the degree requirements, he must take courses from each of several categories. Can you assure Freddie that he will graduate, based on his course selection?

## Input

Input consists of several test cases, at most $50$. For each case, the first line of input contains $1 \le k \le 100$, the number of courses Freddie has chosen, and $0 \le m \le 100$, the number of categories. A line follow containing $k$ $4$-digit integers; each is the number of a course selected by Freddie. Each category is represented by a line containing $1 \le c \le 100$, the number of courses in the category, $0 \le r \le c$, the minimum number of courses from the category that must be taken, and the $c$ course numbers in the category. Each course number is a $4$-digit integer. The same course may fulfil several category requirements. Freddie’s selections, and the course numbers in any particular category, are distinct. A line containing $0$ follows the last test case.

## Output

For each test case, output a line containing “`yes`” if Freddie’s course selection meets the
degree requirements; otherwise output “`no`”.
