Suppose that a university wants to show off how politically correct it is by applying the U.S. Supreme Courts "Separate but equal is inherently unequal doctrine to gender as well as race, ending its long- standing practice of gender-segregated bathrooms on campus. However, as a concession to tradition, it decrees that when a woman is in a bathroom, other women may enter, but no men, and vice versa. For example, if a woman is currently using the restroom and another woman wants to use the restroom, the second woman is allowed to enter. However, if a man wants to use the restroom, he must wait. A sign with a sliding marker on the door of each bathroom indicates which of three possible states it is currently in: Empty Women present Men present In C code using whatever constructs you like (mutexes, condition variables, semaphores, etc.), write the following procedures woman wants to.enter man wants to enter woman leaves man leaves
