Here is a short Python program.

```python
budget = 5
value = 9
height = 2
value = value + 5
budget += value
height -= 3
nums = [9, 7, 7]
rows = nums
rows += [13]
budget += nums[-1]
weight = 5

def measure(v):
    return v * weight

weight += 5
budget += measure(7)

def apply_rate(val):
    height = val * 2 + 1
    return height + 1

depth = apply_rate(6)
budget += height + depth
count = 0
for i in range(5):
    count += i
budget += count
level = height - 9
tally = level // 3
budget += tally

def boost(w, q=[]):
    q.append(w)
    return len(q)

reserve = boost(9)
quota = boost(4)
budget += quota
budget += height * 2
```

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

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

1.  `budget = 5`
2.  `value = 9`
3.  `height = 2`
4.  `value = value + 5` $\rightarrow$ `value = 14`
5.  `budget += value` $\rightarrow$ `budget = 5 + 14 = 19`
6.  `height -= 3` $\rightarrow$ `height = 2 - 3 = -1`
7.  `nums = [9, 7, 7]`
8.  `rows = nums` (Both point to the same list)
9.  `rows += [13]` $\rightarrow$ `nums` is now `[9, 7, 7, 13]`
10. `budget += nums[-1]` $\rightarrow$ `budget = 19 + 13 = 32`
11. `weight = 5`
12. `def measure(v): return v * weight`
13. `weight += 5` $\rightarrow$ `weight = 10`
14. `budget += measure(7)` $\rightarrow$ `measure(7)` returns $7 \times 10 = 70$. `budget = 32 + 70 = 102`
15. `def apply_rate(val):` (Note: `height` inside this function is local)
    *   `height = val * 2 + 1`
    *   `return height + 1`
16. `depth = apply_rate(6)` $\rightarrow$ $6 \times 2 + 1 = 13$; $13 + 1 = 14$. `depth = 14`
17. `budget += height + depth` $\rightarrow$ Global `height` is $-1$. `budget = 102 + (-1) + 14 = 115`
18. `count = 0`
19. `for i in range(5): count += i` $\rightarrow$ $0+1+2+3+4 = 10$. `count = 10`
20. `budget += count` $\rightarrow$ `budget = 115 + 10 = 125`
21. `level = height - 9` $\rightarrow$ $-1 - 9 = -10$. `level = -10`
22. `tally = level // 3` $\rightarrow$ $-10 // 3 = -4$ (Floor division of $-3.33$ is $-4$)
23. `budget += tally` $\rightarrow$ `budget = 125 + (-4) = 121`
24. `def boost(w, q=[]):` (Note: `q` is a mutable default argument)
    *   `q.append(w)`
    *   `return len(q)`
25. `reserve = boost(9)` $\rightarrow$ `q` becomes `[9]`, returns `1`. `reserve = 1`
26. `quota = boost(4)` $\rightarrow$ `q` becomes `[9, 4]`, returns `2`. `quota = 2`
27. `budget += quota` $\rightarrow$ `budget = 121 + 2 = 123`
28. `budget += height * 2` $\rightarrow$ `budget = 123 + (-1 * 2) = 123 - 2 = 121`
