Your clients can only pay for their purchases by inserting coins into the vending machines. Using pseudo code, outline the algorithm for paying for these purchases. Explain your pseudo
code.

(b)..You and an electronic engineering student have teamed up to build a robot for detecting coronavirus
patients and carriers. You have developed an algorithm for use in building and operating the
robot; and you are currently analysing your algorithm. Clearly distinguish between worst-case running time and best-case running time in algorithm analysis; and give relevant practical
examples to illustrate your answer.

(c)..AIT has established a Help Desk at its KCC Campus; and the Officer-in-charge is using a Help Desk
