Trace the execution of the flowchart.

Execution Trace:

1. Initialization: a = 2, b = 3.

2. Loop Condition Check 1: Is b (3) >= 0? Yes.

3. Loop Body 1:

• b = b * 2 - a = 3 * 2 - 2 = 6 - 2 = 4.
• a = a * 2 = 2 * 2 = 4.

Current values: a = 4, b = 4.

4. Loop Condition Check 2: Is b (4) >= 0? Yes.

5. Loop Body 2:

• b = b * 2 - a = 4 * 2 - 4 = 8 - 4 = 4.
• a = a * 2 = 4 * 2 = 8.

Current values: a = 8, b = 4.

6. Loop Condition Check 3: Is b (4) >= 0? Yes.

7. Loop Body 3:

• b = b * 2 - a = 4 * 2 - 8 = 8 - 8 = 0.
• a = a * 2 = 8 * 2 = 16.

Current values: a = 16, b = 0.

8. Loop Condition Check 4: Is b (0) >= 0? Yes.

9. Loop Body 4:

• b = b * 2 - a = 0 * 2 - 16 = 0 - 16 = -16.
• a = a * 2 = 16 * 2 = 32.

Current values: a = 32, b = -16.

10. Loop Condition Check 5: Is b (-16) >= 0? No.

11. End of Loop.

Final values: a = 32, b = -16.
