A closed chain of processes exists, such that each process holds at least one resource needed by the next process in the chain.

Consider a system of consisting of six resources of the same type that are shared by four process. Each processneed at most 3 resources. Show that the system is deadlock free

Deadlock occurs when each process holds a resource and wait for other resource held by an
