P8831 [Chuanzhi Cup #3 Practice Contest] Julian Calendar

Before 1582, any year that is a multiple of $4$ is a leap year. Normally, the numbers of days in January to December are $31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31$. If the year is a leap year, then February has $29$ days. However, a pope found that this rule was not accurate enough and would cause errors. Therefore, starting from 1582, a year that is a multiple of $4$ is a leap year unless it is a multiple of $100$ but not a multiple of $400$. At the same time, to remove the error, it was规定 that the day after October $4$, 1582 is October $15$, 1582, and the dates in between are considered not to exist.  Now you are given a date. Compute how many days have passed from this date to January $1$, year $1$ AD.

Input the data in the format `day month year`, where day is an integer between $1$ and $31$, month is three uppercase letters, and year is an integer between $1$ and $9999$. It is guaranteed that the date is valid and exists. The uppercase letters for months: - January: JAN - February: FEB - March: MAR - April: APR - May: MAY - June: JUN - July: JUL - August: AUG - September: SEP - October: OCT - November: NOV - December: DEC

Output an integer representing the answer.
