(a) Given the following solution for the critical section problem for two processes (the code shown is for processes Pi), show why it does not satisfy the mutual exclusion requirement. Here, turn, flag[i[], and flag[j] are is shared variables, flag[i] and flag[j] are initialized to FALSE and turn initialized to i. do {flag[i] true; turn = i; while (flag[j] && turn ==j); Critical section flag[i] = FALSE; Remainder section} (b) What happens if flag[i] and flag[j] are set to TRUE in the above code
