Get started for freeA new school has exactly 1,000 lockers and exactly 1,000 students. On the first day of school, the students meet outside the building and agree on the following plan: the first student will enter the school and open all the lockers. The second student will then enter the school and close every locker with an even number \((2,4,6,8\), etc.). The third student will then reverse every third locker \((3,6,9,12\), etc.). That is if the locker is closed, he or she will open it; if it is open, he or she will close it. The fourth student will then reverse every fourth locker, and so on until all 1000 students in turn have entered the building and reversed the proper lockers. Which lockers will finally remain open?

A farmer often makes a trip with a squirrel, acorns, and a fox. During each trip he must cross a river in a boat in which he can't take more than one of them with him each time he crosses. Since he often has to leave two of them together on one side of the river or the other, how can he plan the crossings so that nothing gets eaten, and they all get across the river safely?
