16. What does the following program print? int x = 10; void setup() { int 2 times Two (x); println(x); println(z); A. 10, 10, 20 B. 10, 20, 10 c. 10, 20, 20 D. 20, 20, 10 E. 20, 10, 20 int timesTwo (int y) { x = y* 2; println(y); return x;

Given the following Schedule of Three processes P1,P2 and P3 : 

P1----> P2 -----> P3

Knowing that the processes arrived the same time (0ms) and the execution time for them is X,Y,Z respectively .

What is the response time for each of the three processes: 

a. P1=0, P2 = X , P3 = X+Y

b. P1 = X , P2 = Y , P3 = X+Y+Z

c. P1 = 0 , P2 = X+Y , P3 = X+Y+Z

d. None of the above

17. What does the following program print? int x = 10; void setup() { int z = times Two (x); println(x); println (2); A. 10, 10, 20 B. 10, 20, 10 c. 10, 20, 20 D. 20, 20, 10 E20, 10, 20 int timesTwo (int x) { x = x + 2; println(x); return x;
