Problem

Question

A company has decided to promote
interactions between connections
in various departments.
They have created a number of nodes
which are to be connected to form a cluster
to find the above information. The nodes
are described by a 2D grid of 0's and 1's with
n rows and m columns, a cell containing a
zero denotes not working, while a cell
containing a one is a cell that denotes a
working node.
i. e.
(1 and 0), (0 and1) and(0 and ) have no connections.
but (1 and 1) have connection.
=>Input Format
-The first line contains an integer, n,
denoting the number of rows in
gridofNodes
-The next line contains an integer, m,
denoting the number of columns in
gridOfNodes
-Grid values containing only 1's and 0's

=>Input format example
3
7
1011110
0110101
1000001
Sample Output
28

=>Sample Output Explanation
5 nodes in the first row get connected with
4 nodes in the second row, 20 connections.
Then 4 nodes in the second row get
connected with 2 nodes in the third row, 8
connections 20+8 = 28 connectioms in total
