Let P1 and P2 be two processes with critical sections. Consider the following synchronization method used by the processes, where turn1 and turn2 are shared variables, which ar initialized to false. /* P1 */ * P2 */ while (true) { while (true) { turn1 = true; turn2 = true; while (turn2 == true) while (turn1==true) /* Critical Section */ /* Critical Section */ turn1=false; turn2 = false; * Remainder section */ * Remainder section */ a) Does the above synchronization method ensure mutual exclusion? explain b) Does the above synchronization method prevent starvation? explain
