Answer
The loop will execute 5 times and the value returned is 15.
Working
| Iteration | X | Y | Remark |
|---|---|---|---|
| 2 | 50 | Initial values | |
| 1 | 3 | 47 | x = 4 (3 + 1), y = 47 (50 - 3) |
| 2 | 5 | 42 | x = 6 (5 + 1), y = 42 (47 - 5) |
| 3 | 7 | 35 | x = 8 (7 + 1), y = 35 (42 - 7) |
| 4 | 9 | 26 | x = 10 (8 + 1), y = 26 (35 - 9) |
| 5 | 11 | 15 | x = 12 (11 + 1), y = 15 (26 - 11) |
| 12 | 15 | Condition becomes false. Loop terminates. |
