Problem D. Assuming that each read or write operation takes 5 ms, a read or write operation won't be interrupted, Pi are processes reading/writing a shared resource, and the queue waiting for a semaphore is a FIFO (first-in-first-out) queue, for the code to solve the readers-writers problem in Slides 3.39 through 3.41, a. using the structure given in Slide 3.23 and the algorithm in Slide 3.39, define and initialize a binary semaphore variable named rw mutex, a binary semaphore variable named mutex, and an int variable named read count. b. if P1 needs to read at 1 ms, P2 needs to write at 2 ms, P3 needs to read at 3 ms, . draw a time line to illustrate each read/write operation of each process by marking the begining and ending moments of each read/write operation what are the values of rw mutex, mutex, and read count at 0.5 ms, 1.5 ms, 2.5 ms, 3.5 ms, 4.5 ms, 5.5 ms, and 6.5 ms? c. if P1 needs to write at 1 ms, P2 needs to read at 2 ms, P3 needs to read at 3 ms, draw a time line to illustrate each read/write operation of each process by marking the beginning and ending moments of each read/write operation what are the values of rw mutex, mutex, and read count at 0.5 ms, 1.5 ms, 2.5 ms, 3.5 ms, 4.5 ms, 5.5 ms, and 6.5 ms?
