Consider the following scenario and draw resource-allocation graph and the corresponding wait-for graph.

Resource assigned	Process waiting
An instance of resource R1 is assigned to process P5	Process P1 is waiting for resource R2
Another instance of resource R1 is assigned to process P1	Process P2 is waiting for resource R1
An instance of resource R2 is assigned to process P4	Process P3 is waiting for resource R3
An instance of resource R3 is assigned to process P4	Process P3 is waiting for resource R2
Another instance of resource R3 is assigned to process P2	Process P3 is waiting for resource R2
	Process P4 is waiting for resource R1
