*** 66,72 **** Consider two scenarios. In the first scenario, M and N are both 2 but there are thousands of edges on each node. In this case, option 1 is perferred. ! With option 1, the inner loop checks for the existance of an edge between a pair of nodes and outputs the result if found. But because there are only 2 alice and bob nodes each, the inner loop only has to run 4 times and the query is very quick. Option 2 would take --- 66,72 ---- Consider two scenarios.
