CF760A.Petr and a calendar

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.

彼得想为当前月份制作一个日历。为此，他绘制了一个表格，其中列对应周（一周为从周一到周日的连续七天），行对应星期几，单元格中填写日期。例如，2017年1月的日历应如图所示：

已知某个月份及其该月第一天所对应的星期几，彼得想知道他的表格应有多少列？假设该年为平年。

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).

唯一的一行包含两个整数 $m$ 和 $d$（$1 ≤ m ≤ 12$，$1 ≤ d ≤ 7$）—— 分别表示月份（一月为第一个月，十二月为第十二个月）和该月第一天的星期几（1 表示星期一，7 表示星期日）。

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

输出一个整数：表格应具有的列数。

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.

第一个示例对应题目描述中图片所示的 2017 年 1 月。

第二个示例中，1 月 1 日是星期一，因此整个月恰好占据 5 列。

第三个示例中，11 月 1 日是星期六，且 5 列已足够。
