For this reason, the government is exploring ways to optimize resources for the well-being of society. One aspect they\u0027re considering is energy management in urban areas. Previously, all street lights used to remain on throughout the night, incurring a significant cost of 1 Boliviano per meter and day. To conserve energy and cut down expenses, they have decided to implement a new approach to street lighting. This approach involves selectively turning off some lights on certain streets during certain hours. However, the government also wants to ensure the safety of citizens. Therefore, they are searching for a strategy to manage the lighting in such a way that even with lights turned off in certain areas, there will always be at least one illuminated path from any intersection to any other intersection.\u003c/p\u003e\n\u003cp\u003e\n\tWhat is the maximum daily savings that the government of Bolivia can achieve without compromising the sense of security for its inhabitants?\u003c/p\u003e\n\u003ch4\u003e\n\tInput Specification\u003c/h4\u003e\n\u003cp\u003e\n\tThe input file contains several test cases.
