说明

Polar bears use the Gregorian calendar. It is the most common calendar and you likely use it too. You can read about it on Wikipedia if you want to – [https://en.wikipedia.org/wiki/Gregorian\_calendar](https://en.wikipedia.org/wiki/Gregorian_calendar). The week starts with Monday. In the first sample Limak wants to save one candy on each Thursday (the 4-th day of the week). There are $ 52 $ Thursdays in the 2016. Thus, he will save $ 52 $ candies in total. In the second sample Limak wants to save one candy on the 30-th day of each month. There is the 30-th day in exactly $ 11 $ months in the 2016 — all months but February. It means that Limak will save $ 11 $ candies in total.
