Suppose process P 0 uses variables V 0 and V 1 at the same time, process P 1 uses variables V 1 and V 2 at the same time, and process P 2 uses variables V 2 and V 0 at the same time Further, P 0 , P 1 , and P 2 run concurrently Write a code fragment using the simultaneous semaphore operations to coordinate access to V 0 , V 1 , and V 2 so that the critical section problem does not occur

Question: Suppose process P 0 uses variables V 0 and V 1 at the same time, process P 1 uses variables V 1 and V 2

Suppose process P₀ uses variables V₀ and V₁ at the same time, process P₁ uses variables V₁and V₂ at the same time, and process P₂uses variables V₂and V₀ at the same time. Further, P₀, P₁, and P₂ run concurrently. Write a code fragment using the simultaneous semaphore operations to coordinate access to V₀, V₁, and V₂so that the critical section problem does not occur.
