Here is a short Python program.

```python
peak = 3
height = 2
values = [7, 5, 9]
height = len(values) % 3
peak += height * 2
bins = [9, 2, 1]
parts = bins
parts.append(19)
peak += bins[-1]
quota = 5

def boost(val):
    return val + quota

quota = 8
peak += boost(7)
for j in range(5):
    peak += j * 3
extra = height - 3
size = extra // 4
peak += size

def shift_by(n, q=[]):
    q.append(n)
    return len(q) + n

step = shift_by(4)
tally = shift_by(1)
peak += step + tally
peak += len(values)
```

After this program runs, what is the value of `peak`? 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 to determine the final value of `peak`.

1. `peak = 3`
2. `height = 2`
3. `values = [7, 5, 9]`
4. `height = len(values) % 3`  `height = 3 % 3 = 0`
5. `peak += height * 2`  `peak = 3 + 0 * 2 = 3`
6. `bins = [9, 2, 1]`
7. `parts = bins`  `parts` now refers to the same list as `bins`.
8. `parts.append(19)`  `bins` becomes `[9, 2, 1, 19]`
9. `peak += bins[-1]`  `peak = 3 + 19 = 22`
10. `quota = 5`
11. `def boost(val): return val + quota`
12. `quota = 8`
13. `peak += boost(7)`  `peak = 22 + (7 + 8) = 22 + 15 = 37`
14. `for j in range(5): peak += j * 3`
   - `j = 0`: `peak = 37 + 0 * 3 = 37`
   - `j = 1`: `peak = 37 + 1 * 3 = 40`
   - `j = 2`: `peak = 40 + 2 * 3 = 46`
   - `j = 3`: `peak = 46 + 3 * 3 = 55`
   - `j = 4`: `peak = 55 + 4 * 3 = 67`
15. `extra = height - 3`  `extra = 0 - 3 = -3`
16. `size = extra // 4`  `size = -3 // 4 = -1`
17. `peak += size`  `peak = 67 + (-1) = 66`
18. `def shift_by(n, q=[]): q.append(n); return len(q) + n`
19. `step = shift_by(4)`  `q` is initialized as `[]`. `q.append(4)`, `q` is now `[4]`. `len(q) + n = 1 + 4 = 5`. `step = 5`
20. `tally = shift_by(1)`  `q` is still `[4]` from the previous call. `q.append(1)`, `q` is now `[4, 1]`. `len(q) + n = 2 + 1 = 3`. `tally = 3`
21. `peak += step + tally`  `peak = 66 + 5 + 3 = 74`
22. `peak += len(values)`  `peak = 74 + 3 = 77`
