23. What does the following program print? void setup() { int x = 10; timesTwo (x); println(x); A. 10,20 B. 20, 10 C. 20,20 void timesTwo (int x) { x = x + 2; println(x);

23. Consider again the array a = {5,7,1,4,1} and the Selection Sort (code 2) algorithm. What is the last value of the variable minPos, before the algorithm exits? (A) 0 (B) 4 (C) 2 (D) 5 (E) 1

31. What is printed by the following code in base 2? int sum = 0; for (int x = 0; x< 5; x++) sum+=x; System.out.println(sum); 21 x 21 + 0 x 23+1 22 +1 x 21 +1 x 20
