: Both processes can never be in the critical section at the same time because the turn variable cannot be two values simultaneously.

enters a loop: while (flag[j] && turn == j); . It stays here as long as the other process is interested it is currently that process's turn. Critical Section : Once the loop condition is false, Picap P sub i enters the critical section. Exit : Upon leaving, Picap P sub i 2 klass peterson algoritm

: A boolean array where flag[i] = true indicates that process Picap P sub i wants to enter its critical section. : Both processes can never be in the

: If no one is in the critical section and a process wants to enter, it will not be blocked by processes outside their critical sections. Critical Section : Once the loop condition is

: A process will wait at most one turn before it is granted access, ensuring no starvation. Modern Limitations
