Problem statement
Suppose there are n cities, where some are connected, while others are not.
If a city c1 is connected to city c2, and city c2 is connected to city c3, then c1 is indirectly connected to c3.
A group of directly or indirectly connected cities, where no other city is part of this group, is called a province.
You are given a matrix, is_connected with a size of n x n. An entry is_connected[i][j] = 1 if the ...
