There are n buildings in campus. david doesn’t have a good memory, so he wants to choose n - 1 roads that, from any building in the campus, he can get to any building he wants. however, david doesn’t want to walk too much, so he also wants total length of all roads to be minimum. your task is to david to find those n - 1 roads. for the simplicity of the problem, instead of using building’s name, we will use the building’s number, so there are n buildings from 0 to n - 1. in map. java, implement the following method:
int mindistance(int[][] dists): takes an input of a 2-d integers array where dists[i][j]
is the distance of a single road from building i to building j (note that dists[i][i] is always 0
and dists[i][j] = dists[j][i] > 0 when i ! = j). returns the minimum total distance of n - 1
roads. for example, giving this 2-d array:
0 1 2 10
1 0 3 4
2 3 0 3
10 4 3 0
your method should return 6 because the roads david should choose are 0 - 1; 0 - 2; 2 - 3.
also include the main method in map. java to test at least 3 scenarios with n > 4
