A system with 5 processes P0 through P4 and three resource types A, B, C have A with 10 instances, B with 5 instances, and C with 7 instances. At time t0, the following snapshot has been taken: Process P0 P1 P2 P3 P4 Allocation (process-wise : P0 through P4 top TO bottom) A B C 0 1 0 2 0 0 3 0 2 2 1 1 0 0 2 MAX (process-wise: P0 through P4 top TO bottom) A B C 7 5 3 3 2 2 9 0 2 2 2 2 4 3 3 Available A B C 3 3 2 The sequence <P1, P3, P4, P2, P0> leads the system to
