Fill in the blanks below. All questions carry equal points.
1. Suppose the input array is A = <13, 19, 9, 5, 12, 8, 7, 4, 11, 2, 6, 21>
A. At the end of the first iteration of the while loop of Line 4, the integer at index 0 of
A is
B. At the end of the first iteration of the while loop of Line 4, the integer at index 11
of A is
C. When ALGO terminates, the integer at index 4 is
D. When ALGO terminates, the integer at index 9 is
E. The value of r returned by ALGO in Line 12 is
