Question 1: Consider a system with four processes and four resources as follows: - P is a set of processes as P={P1,P2,P3,P4} - R is a set of resources as R={R1,R2} R1 and R2 have two instances. The Snapshot at time T0 has the following situation: - P1 allocates an instance of R1 while requesting an instance of R2. - P2 allocates an instance of R1 while requesting an instance of R2. - P3 allocates an instance of R2 while requesting an instance of R1. - P4 allocates an instance of R2 while requesting an instance of R2. 1- Draw the resource allocation graph. 2- Is there a cycle in the graph? If yes, determine it. 3- Is the system in deadlock? Show your work and explain your
