Use the following scenario to answer the question below:  Joe’s biology class was studying the effects of different wavelengths of light on the process of photosynthesis in bean plants.  Four flats of bean plants (25 plants per flat) were grown for five days. The plants were then exposed to different colors of light as follows: Flat A was placed under red light; Flat B was placed under blue light; Flat C was placed under green light; and Flat D was placed under white light. The plants were exposed to the same temperature conditions and received the same amount of water and carbon dioxide each day. At the end of 20 days, the students recorded the height of the plants in centimeters. What was the independent variable in the experiment?

Five processes (A, B, C, D, and E) will each use a block of code that is shareable but can be used by only one process at a time. These processes will use a semaphore to control access to the critical section (CS). Q1: What should the initial value of the semaphore counter be?
