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>`.

To find the value of `extra`, let's trace the program step-by-step:

1.  `extra = 4`
2.  `limit = 4`
3.  `cost = 1`
4.  `extra += limit` $\rightarrow$ `extra = 4 + 4 = 8`
5.  `if limit < limit:` $\rightarrow$ `4 < 4` is **False**.
6.  Enter `else` block:
    *   `cost += 8` $\rightarrow$ `cost = 1 + 8 = 9`
    *   `limit = extra - 2` $\rightarrow$ `limit = 8 - 2 = 6`
7.  `if cost > extra:` $\rightarrow$ `9 > 8` is **True**.
    *   `limit -= extra` $\rightarrow$ `limit = 6 - 8 = -2`
    *   `limit = limit if limit > extra else extra + 2` $\rightarrow$ `-2 > 8` is False, so `limit = 8 + 2 = 10`
8.  `if cost == 1:` $\rightarrow$ `9 == 1` is **False**.
9.  Enter `else` block:
    *   `limit = limit + 4` $\rightarrow$ `limit = 10 + 4 = 14`
10. `limit = extra if extra > cost else cost + 1` $\rightarrow$ `8 > 9` is False, so `limit = 9 + 1 = 10`
11. `def boost(arg, num=5):` (Function defined, not called).
12. `if cost >= 3:` $\rightarrow$ `9 >= 3` is **True**.
    *   `limit = extra * 2` $\rightarrow$ `limit = 8 * 2 = 16`
13. `cost = extra if extra < extra else extra + 2` $\rightarrow$ `8 < 8` is False, so `cost = 8 + 2 = 10`

Throughout the execution, the variable `extra` was modified only once at the beginning (`extra += limit`). No subsequent operations changed the value of `extra`.

Final value of `extra`: 8

ANSWER: 8
