Repeat the previous problem, but now avoid starvation. When a baboon that wants to cross to the east arrives at the rope and finds baboons crossing to the west, he waits until the rope is empty, but no more westward-moving baboons are allowed to start until at least one baboon has crossed the other way. 29. Write a program to implement the deadlock detection algorithm with multiple resources of each type. Your program should read from a file the following inputs: the number of processes, the number of resource types, the number of resources of each type in existence (vector E), the current allocation matrix C (first row, followed by the second row, and so on) the request matrix R (first row, followed by the second row, and so on). The output of your program should indicate if there is a deadlock in the system or not. In case there is a deadlock in the system, the program should print out the identities of all processes that are deadlocked. MULTIMEDIA OPERATING SYSTEM 30. Write a program that detects if there is a deadlock in the system by using a resource allocation graph. Your program should read from a file the following inputs: the number of processes and the number of resources. For each process if should read four numbers: the number of resources it is currently holding, the IDs of resources it is holding, the number of resources it is currently requesting, the IDs of resources it is requesting. The output of program should indicate if there is a deadlock in the system or not. In case there is a deadlock in the system, the program should print out the identities of all processes that are deadlocked. Digital movies, video clips, and music are becoming an increasingly common way to present information and entertainment using a computer. Audio and video files can be stored on a disk and played back on demand. However, their characteristics are very different from the traditional text files that current file systems were designed .
