Hey i can't figure out how to do this program, would any of ye could give a hand?
"Postman Pat became bored one night at the postal sorting office and to break the monotony of the nightshift, he carried out the following experiment with a row of mailboxes (all initially closed) in the post office. These mailboxes are numbered 1 through to 150, and beginning with mailbox 2, he opened the doors of all the even-numbered mailboxes. Next, beginning with mailbox 3, he went to every third mailbox, opening its door if it was closed and closing it if it was open. Then he repeated this procedure with every fourth door, then every fifth door, and so on. When he finished, he was surprised at the distribution of closed mailboxes. Write a program to determine and display which mailboxes these were (i.e. which doors were closed at the end of the process)."
