Here is a short Python program.

```python
extra = 4
limit = 4
cost = 1
extra += limit
if limit < limit:
    cost = extra if extra > cost else cost + 4
    extra += cost
else:
    cost += 8
    limit = extra - 2
if cost > extra:
    limit -= extra
    limit = limit if limit > extra else extra + 2
if cost == 1:
    cost = limit * 2
    cost = limit + 7
else:
    limit = limit + 4
limit = extra if extra > cost else cost + 1

def boost(arg, num=5):
    return arg * 2 + num

if cost >= 3:
    limit = extra * 2
cost = extra if extra < extra else extra + 2
```

After this program runs, what is the value of `extra`? Work through it carefully, then give the final answer on its own last line as `ANSWER: <python literal>`.

Let's trace the execution of the Python code step by step:

1. `extra = 4`
2. `limit = 4`
3. `cost = 1`
4. `extra += limit`  => `extra = 4 + 4 = 8`
5. `if limit < limit:` (i.e., `4 < 4`) is false.
6. `else:` block is executed.
7. `cost += 8` => `cost = 1 + 8 = 9`
8. `limit = extra - 2` => `limit = 8 - 2 = 6`
9. `if cost > extra:` (i.e., `9 > 8`) is true.
10. `limit -= extra` => `limit = 6 - 8 = -2`
11. `limit = limit if limit > extra else extra + 2` (i.e., `limit = -2 if -2 > 8 else 8 + 2`) => `limit = 10`
12. `if cost == 1:` (i.e., `9 == 1`) is false.
13. `else:` block is executed.
14. `limit = limit + 4` => `limit = 10 + 4 = 14`
15. `limit = extra if extra > cost else cost + 1` (i.e., `limit = 8 if 8 > 9 else 9 + 1`) => `limit = 10`
16. `def boost(arg, num=5):` defines a function, but it's not called.
17. `if cost >= 3:` (i.e., `9 >= 3`) is true.
18. `limit = extra * 2` => `limit = 8 * 2 = 16`
19. `cost = extra if extra < extra else extra + 2` (i.e., `cost = 8 if 8 < 8 else 8 + 2`) => `cost = 10`

The final value of `extra` is 8.

ANSWER: 8
