    Thanks for making those spammers pay every day.
    Congrats! Do you need someone to hold that long train?
    Not that I am saying you are royalty, nay!

    A tribute, to show P.A.'s appreciation.
    Thank you, for all the laughs, all the quirky comments.

    There are 1000 pupils on my school, so there are exactly 1000 lockers, and they are all closed at this moment. All the lockers got a number from 1-1000. Our school principle decides to play a stupid game, she has given each of us a number. Number 1 opens all the lockers, number 2 changes all the lockers(closes it) with the numbers that can be divivded by 2, so locker 2,4,6,8 etc will be closed. Then number 3 changes(opened when the locker is closed and vice versa) all the lockers with the numbers that can be divided by 3 (locker 3,6,9,12,15 etc) etc etc etc...
    So after pupil number 1000 has done its work, how many lockers remain open and what are the numbers of the lockers?

    -------------------------------

    if a number is a perfect square, then it'll have an odd number of factors. all other numbers have an even number of factors. if a locker is changed an odd number of times, then it'll be open at the end. if a locker is changed an odd number of times, then it'll be open, because the first student opens it, the second student closes it, the third student opens it, and so on. so to find the numbers of the lockers that are still open, we have to find the ones that were changed an odd number of times, which are the ones with an odd number of factors. the only numbers with an odd number of factors are perfect squares. so we just have to find the perfect squares between 1 and 1000.


    1,4,9,16,25,36,49,64,81,100,121,144,169,196,225,256,289,324,361,400,441,
    484,529,576,625,676,729,784,841,900,961

    that's 31, so there were 31 lockers open
