Exercise: You will write a program to simulate the routing decision taken at a router that we discussed in

the lectures. You are given a text file (Routing Table.txt) containing a routing table for a router (the five

column generic routing table with mask, destination address, next hop, flag and interface). You will notice

that this is almost the same routing table as the one that we discussed in the lectures. The first few lines of

the text file are shown below.
