Suppose processes P 0 and P 1 share variable V 2 , processes P 1 and P

Question:

Suppose processes P₀ and P₁share variable V₂, processes P₁ and P₂ share variable V₀, and processes P₂ and P₃ share variable V₁.

a. Show how the processes can use enableInterrupt ( ) and disableinterrupt ( ) to coordinate access to V₀, V₁, and V₂ so that the critical section problem does not occur.

b. Show how the processes can use semaphores to coordinate access to V₀, V₁, and V₂ so that the critical section problem does not occur.
