Hint: Look at a smaller set of lockers. How many lockers (and which ones specifically) are open when there are only 10 lockers involved? Then find out how many (and which ones specifically) are open when 100 lockers are considered. Keep doing this until you start to see a pattern. If you're having trouble seeing a pattern, try smaller increments (ie go from 10 to 20, then to 30, etc...)
