Problem Statement
Let's number the days of the week as follows: Sunday=0, Monday=1, Tuesday=2, Wednesday=3, Thursday=4, Friday=5 and Saturday=6.
You are given two numbers:
- firstDay: a value from {0,1,2,3,4,5,6} telling you which day of the week is January 1st.
- isLeap: a value from {0,1} that is 1 if the year is a leap year and 0 if it's not.
In an ordinary year the months have the following numbers of days: 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31. In a leap year February has 29 days instead of 28.
