The major problem with the electric cars is the battery capacity. The batteries used in these cars are generally very heavy and expensive, so engineers must make important trade-offs when determining the battery capacity, and therefore the range, of these vehicles. Suppose that the road network is defined by an undirected weighted graph G = (V, E). The vertices represent the cities, the edges represent the distance between the two cities, and the weight represents the distance between two cities. Assume that each city has EV charger stations so that the driver can charge the car's battery. Write an O (E log |E|) algorithm to determine the minimum range of the car that enables it to drive from every city to every other city.

Question
The major problem with the electric cars is the battery capacity. The
batteries used in these cars are generally very heavy and expensive, so
engineers must make important trade-offs when determining the battery
capacity, and therefore the range, of these vehicles.
Suppose that the road network is defined by an undirected weighted graph
G = (V, E). The vertices represent the cities, the edges represent the
distance between the two cities, and the weight represents the distance
between two cities. Assume that each city has EV charger stations so that
the driver can charge the car's battery. Write an O (E| log |E|) algorithm
to determine the minimum range of the car that enables it to drive from
every city to every other city.
