The following code fragment is a 2-process “solution” to the critical section problem. try[i] = true; while (incs[j]) no-op; while (turn=j and try[j]) no-op; incs[i] = true; critical section try[i] = false; incs[i] = false; turn = j; does the above “solution” have mutual exclusion? explain your answer.
