Petr and a calendar

# 题目描述 PETR这个人想写一个2017年一个月的日期表，日期从上往下，从左往右写。第一行代表周一，第二行代表周二，...，第七行代表周日。如：2017年一月1号是周日，则17年一月的日历写成： ``` 2 9 16 23 30 3 10 17 24 31 4 11 18 25 5 12 19 26 6 13 20 27 7 14 21 28 1 8 15 22 29 ``` 你要求出日历有几列。 # 输入输出 正整数m,d(1<=m<=12,1<=d<=7). m表示月份，d表示本月第一天是周几。 输出日历有几列。

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: Petr wants to know how many columns his table should have given the month and the weekday of the first date of that month? Assume that the year is non-leap.

The only line contain two integers $ m $ and $ d $ ( $ 1<=m<=12 $ , $ 1<=d<=7 $ ) — the number of month (January is the first month, December is the twelfth) and the weekday of the first date of this month ( $ 1 $ is Monday, $ 7 $ is Sunday).

Print single integer: the number of columns the table should have.

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.
