Consider the single-server queue with geometrically distributed inter-arrival times and service times as discussed in class, with a departure rate of = 0:5. Plot the expected delay of a job as a function of the arrival rate . You have to run the simulations long enough, for example at least for 10^6 time slots.

Note: Choose one programming language to do the simulation from C/C++, Matlab, Python, and Java. Report should include the plot, and simulation code and annotations.
