Number of Provinces - There are n cities. Some of them are connected, while some are not. If city a is connected directly with city b, and city b is connected directly with city c, then city a is connected indirectly with city c. A province is a group of directly or indirectly connected cities and no other cities outside of the group.
Your task is to complete the function numProvinces () which takes an integer V and an adjacency matrix adj (as a 2d vector) as input and returns the number of provinces. adj [i] [j] = 1, if nodes i and j are connected and adj [i] [j] = 0, if not connected.

May 30, 2017 · 547. Number of Provinces. There are n cities. Some of them are connected, while some are not. If city a is connected directly with city b, and city b is connected directly with city c, then city a is connected indirectly with city c. A province is a group of directly or indirectly connected cities and no other cities outside of the group.
A province is a group of directly or indirectly connected cities and no other cities outside of the group. You are given an n x n matrix isConnected where isConnected [i] [j] = 1 if the ith city and the jth city are directly connected, and isConnected [i] [j] = 0 otherwise.
Return the total number of provinces. Example 1 Input: 3 3 1 1 0 1 1 0 0 0 1 Output: 2 Explanation: This 3 3 matrix represent the connection between the cities, as we can see value of 1st raw and 2nd column is 1,This means city 1 and city 2 are connected so this collectively form one province and city 3 individually behaving as province.
