answer this question and make a race with me RIGHT NOW! [ROUND 2]

[MrCoolness 547]

A mailman runs the same route of 1000 mail boxes every day on a crescent. One day he gets bored and decides to do his job a little differently. He goes to every single mailbox and opens it, then he returns to the beginning and closes every other (mailbox 2,4,6...) mailbox, then he returns to the beginning and does the same thing to every third mailbox (3,6,9...) and if the mailbox was open he closes it and if the mailbox was closed he opens it, then every 4th mailbox... every 5th... and so forth...

 

He repeats this until he goes to every "1000'th" mailbox, meaning he goes to the last mailbox and opens/closes it and then calls it a day.

 

When the mailman looks back at what he's done, which mailboxes are still open?

would it by any chance be just 2?

[AntyCrix 591]

The mailboxes that are still open are the mailboxes whose owners didn't go out to check their mail

 

Actually none of them because people should have already checked their mail

Think in factors. Well, primes would have to be closed (opened once and then closed whenever you count by itself) and squares would be open (odd number of factors).

So assuming it's all the squares from 1-1000.

1, 4, 9 , 16, 25, 36, etc etc on my phone too lazy to count them all out
