DWITE Online Computer Programming Contest, January 2010, Problem 1

As social media gets more popular, there are all kinds of people beginning to join online social networks. Some want to better connect with their friends, others amass a following to spam to with the links to their blog (on the topics of amassing online followings…), while yet another group has relapsed into their childhood memories of catching them all. At what point does "friending" turn into a game? Let's try to find out.

The input will contain 5 lines, integers ~1 \le N \le 9000~, a number of "friends" in one's social network.

The output file will contain 5 lines, each corresponding to the corresponding result, an integer (rounded to closest whole number) number of minutes each "friend" gets dedicated to them, in a month, assuming a month means 30 days, and there are 5 hours of solid non-stop online socializing happening with this particular network.

For example: there are ~30 \times 5 = 150~ hours of available time, so for those with 150 contacts, each contact gets, on average, just 1 hour (60 minutes), of personal attention per month.
