correcting ... Its minimum numbers of ladders required
Please suggest how you think for this problem Suppose you have many airplanes . Each plane needs a ladder so that people can board the plane easily . Now plane will land at time land_time and then fly away again at fly_time . During this time , people will continue to board the plane and the ladder should remain attached to the plane. So if plane lands at 3 am and fly at 3 pm , we need a ladder from 3 am to 3 pm dedicated for that plane. Given land_time and fly_time of multiple planes in a day , find the minimum number of ladders your require . --mac On Fri, Oct 1, 2010 at 3:56 PM, Yan Wang <[email protected]> wrote: > I think your question should be to find the minimum number of ladders > required. > > This is a very classic Greedy-Algorithm solved problem.
