Understand the following algorithm. Simulate it mentally on the following four inputs, and state the outputs produced (value returned) in each case: (a) A: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; (b) A: [‐1, ‐2, ‐3, ‐4, ‐5, ‐6, ‐7, ‐8, ‐9, ‐10]; (c) A: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]; (d) A: [‐1, 2, ‐3, 4, ‐5, 6, 7, ‐8, 9, ‐10].
