4. (6 pts.) Consider the following state of a system with four processes P1,P2,P3 and P4, and five types of resources RS1, RS2, RS3, RS4 and RSS. Use deadlock detection algorithm for multiple resources of different types to show whether the system is free of deadlock or not. Note: Show all the necessary steps. ( E= Existing resources, A= Available resources, C= Current resources and R=R Requested resources) E=(3,4,1,4,5)andA=(0,1,0,2,2)
