Prompt
Here is a short Python program.
```python
level = 5
limit = 5
delta = 4
level += delta
delta = limit - 9
delta += 9
def scale(v):
m = v + 5
return m * 2
values = [3, 5, 6]
parts = values
parts += [16]
parts = parts + [22]
rows = values[:]
rows.append(31)
level += len(values) + values[-1]
extra = 1
offset = 0
while extra < 41:
extra += 5
offset += 1
level += offset + extra
level += limit
```
After this program runs, what is the value of `level`? Work through it carefully, then give the final answer on its own last line as `ANSWER: <python literal>`.
Response
To find the final value of `level`, let's trace the program step-by-step:
1. `level = 5`
2. `limit = 5`
3. `delta = 4`
4. `level += delta` $\rightarrow$ `level = 5 + 4 = 9`
5. `delta = limit - 9` $\rightarrow$ `delta = 5 - 9 = -4`
6. `delta += 9` $\rightarrow$ `delta = -4 + 9 = 5`
7. The function `scale(v)` is defined but never called.
8. `values = [3, 5, 6]`
9. `parts = values` (Both `parts` and `values` now point to the same list object `[3, 5, 6]`)
10. `parts += [16]` $\rightarrow$ This modifies the list in place. `values` and `parts` are now `[3, 5, 6, 16]`
11. `parts = parts + [22]` $\rightarrow$ This creates a new list. `parts` is now `[3, 5, 6, 16, 22]`, but `values` remains `[3, 5, 6, 16]`
12. `rows = values[:]` $\rightarrow$ `rows` is a copy: `[3, 5, 6, 16]`
13. `rows.append(31)` $\rightarrow$ `rows` is now `[3, 5, 6, 16, 31]`. This does not affect `values`.
14. `level += len(values) + values[-1]`
* `len(values)` is 4.
* `values[-1]` is 16.
* `level = 9 + 4 + 16 = 29`
15. `extra = 1`
16. `offset = 0`
17. `while extra < 41:`
* Iteration 1: `extra = 1 + 5 = 6`, `offset = 0 + 1 = 1`
* Iteration 2: `extra = 6 + 5 = 11`, `offset = 1 + 1 = 2`
* Iteration 3: `extra = 11 + 5 = 16`, `offset = 2 + 1 = 3`
* Iteration 4: `extra = 16 + 5 = 21`, `offset = 3 + 1 = 4`
* Iteration 5: `extra = 21 + 5 = 26`, `offset = 4 + 1 = 5`
* Iteration 6: `extra = 26 + 5 = 31`, `offset = 5 + 1 = 6`
* Iteration 7: `extra = 31 + 5 = 36`, `offset = 6 + 1 = 7`
* Iteration 8: `extra = 36 + 5 = 41`, `offset = 7 + 1 = 8`
* Loop ends because `extra < 41` is now false (41 is not less than 41).
18. `level += offset + extra`
* `level = 29 + 8 + 41 = 78`
19. `level += limit`
* `level = 78 + 5 = 83`
