题目描述
Petr wants to make a calendar for current month. For this purpose he draws a table in which columns correspond to weeks (a week is seven consequent days from Monday to Sunday), rows correspond to weekdays, and cells contain dates. For example, a calendar for January 2017 should look like on the picture:

The first example corresponds to the January 2017 shown on the picture in the statements.
In the second example $ 1 $ -st January is Monday, so the whole month fits into $ 5 $ columns.
In the third example $ 1 $ -st November is Saturday and $ 5 $ columns is enough.
