Problem B
Dagatal

Probably one of the oddest details of the Gregorian calendar is the distribution of the number of days in a month. The distribution seems pretty random, even though there is a reason for it being how it is. This confuses many and they often have a hard time remembering the number of days in a month. Write a program to help these poor souls. The program should assume the year is $2019$.

Input

One line with a single integer $m$, the number of the month. It will hold that $1 \leq m \leq 12$.

Output

A single line with one integer, the number of days in month number $m$.
