- 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?

Do not copy. Correct code will upvoted else downvote. Monocarp is playing a PC game. Presently he needs to finish the principal level of this game. A level is a rectangular framework of 2 lines and n sections. Monocarp controls a character, what begins in cell (1,1) — at the convergence of the 1-st line and the 1-st segment. Monocarp's character can move starting with one cell then onto the next in one stage if the cells are nearby by side or potentially corner. Officially, it is feasible to move from cell (x1,y1) to cell (x2,y2) in one stage if |x1−x2|≤1 and |y1−y2|≤1. Clearly, it is denied to go external the matrix. There are traps in certain cells. In case Monocarp's character winds up in such a cell, he bites the dust, and the game closures. To finish a level, Monocarp's character should arrive at cell (2,n) — at the crossing point of line 2 and section n. Assist Monocarp with deciding whether it is feasible to finish the level. Input The principal…
