The organizers were worried that a tall bus might not pass under one of them. They know the height of each of the bridges. The bus can pass under the bridge if and only if the height of the bridge exceeds the height of the bus. Help the organizers find out if the tour will end safely, and if not, determine where the accident will occur.
