There are 100 lockers, and 100 students, each student is assigned a locker #1-100. All of the lockers start out closed, and each student goes through and changes the state (opens or closes) of each locker that is a multiple of his locker number. (i.e. locker #1 student will open every locker, while locker #2 student will close every even number locker, because even numbers are a multiple of 2)
At the end, which lockers will be open, and why?
