Suppose that a programmer has written the following Marie-Sim code on his computer A to add two vectors X={X1, X2, X3...} and Y={Y1, Y2, Y3...} and to stores it as Z={Z1, Z2, Z3...}. The initial values of all Zis are all 0 (as shown).

Once Computer A has executed and stored the values, the programmer wants to multicast this data on Z to certain devices connected via the internet (another application will output this data in the memory). Two networks have 134.34.89.0/24 (Net1) and 122.8.7.4/29 (Net 2) as their CIDR IP addresses. The destinations hosts are on these two networks. From computer A the round-trip time (RTT) to any host machine on the first network (Net 1) is 5 ms whereas the RTT to any host on the second network (Net 2) is 10 ms respectively. Suppose that RTT represents the end-to-end time to transmit all the packets containing the data and receive acknowledgement from the target destination. Computer A sends the data to each possible host on Net 1 one after the other followed by transmission in similar manner to each possible host on Net 2.

(continued from above)

a. What would this program really store for the vector Z? Show the first few values of Z1, Z2, Z3,... etc.
b. How long does it take the computer to execute just the code itself? 
c. How long does it take computer A to then send the data to each and every machine on Net1 and Net 2 and receive acknowledgement?
