Nikifor claimed that it is possible to color some
observers, and the summary time when there was only one
colored observer in the room is not less than 2/3 of the
time

the input says that 2nd is from 0 10 and
                    5th is from 9 18 so they cross and
                    they are also coloured which means it
                    is wrong!
Please tell me why it is right!
