Question 1

Consider the following small Java program. What will the contents of the array x be when the code finishes running?

public class Driver { public static void main(String[ ] args) { int[ ] x = {3,1,5,2,4}; int a = 0; for (int index = 0; index < x.length - 1; index++) { if ( x[index] > x[index + 1]) { a = x[index]; x[index] = x[index + 1]; x[index + 1] = a; } } } }

1,2,4,3,5

1,3,2,5,4

None of these.

3,1,2,4,5

1,3,2,4,5

2,1,3,5,4

3,4,1,5,2

2,1,3,5,4

5,4,3,2,1

1,2,3,4,5
