Process P1 init (mutEx); num = 0; loop1 = 0; while (loop1 < 3) wait (mutEx); num num + 1; signal (mutEX); loop1 loop1 + 1; Process P2 loop2 = 0; while (loop2 < 2) wait (mutEx); num num + 10; signal(mutEX); loop2loop2 + 1; Assume all variables are shared for P1 and P2. This is a single core system. We will start with P1. The CPU will execute 5 lines of code before switching processes. What is the value of num after both processes finish executing?
