The first known correct software solution to the critical-section problem for n processes with a lower bound
Question:
enum pstate {idle, want in, in cs};
pstate flag[n];
int turn;
All the elements of flag are initially idle; the initial value of turn is immaterial (between 0 and n-1). The structure of process Pi is shown in Figure 6.26. Prove that the algorithm satisfies all three requirements for the critical-section problem.
