- school has 100 lockers and 100 students. All lockers areclosed on the first day of school. As the students enter, the first student, denotedas S1, opens every locker. Then the second student, S2, begins with the secondlocker, denoted as L2, and closes every other locker. Student S3 begins with thethird locker and changes every third locker (closes it if it was open and opens it ifit was closed). Student S4 begins with locker L4 and changes every fourth locker.Student S5 starts with L5 and changes every fifth locker, and so on, until studentS100 changes L100.After all the students have passed through the building and changed the lockers,which lockers are open?
