Problem: http://uva.onlinejudge.org/external/3/352.html
My Approach:

• Traverse all elements starting from 0,0
• Check whether the element is one
• If it is the applydfs
• applydfs
• if it is one, mark it as 0
• apply the same to all its unvisited neighbours
• if zero, return
• count the no. of times dfs is applied
• this will count the number of connected components
• And thus we have our answer
