Input
The input is given from Standard Input in the following format:
N A B
$D_1 D_2 \ldots D_N$
Output

In this input, a week consists of seven days, with the first through second days being holidays and the third through seventh days being weekdays.
Let us assume today is the seventh day of the week. In this case, one day later would be the first day of the week, two days later would be the second day of the week, and nine days later would also be the second day of the week, making all plans scheduled on holidays. Therefore, it is possible for all of Takahashi's N plans to be scheduled on holidays.
