Prompt
Here is a short Python program.
```python
tally = 4
width = 2
credit = 3
tally += width
width = credit * 2
tally += credit * 2
credit = tally if tally > width else width + 9
width = width * 2
width = width - 9
credit = tally * 2
if width > credit:
width -= width
credit = credit * 2
else:
credit = width * 3
credit = credit * 2
if width < 6:
width -= tally
credit = tally + 4
else:
width = tally * 2
credit += credit
width -= width
width -= width
```
After this program runs, what is the value of `tally`? Work through it carefully, then give the final answer on its own last line as `ANSWER: <python literal>`.
Response
To find the value of `tally`, let's trace the program step-by-step:
1. `tally = 4`
2. `width = 2`
3. `credit = 3`
4. `tally += width` $\rightarrow$ `tally = 4 + 2 = 6`
5. `width = credit * 2` $\rightarrow$ `width = 3 * 2 = 6`
6. `tally += credit * 2` $\rightarrow$ `tally = 6 + (3 * 2) = 6 + 6 = 12`
7. `credit = tally if tally > width else width + 9`
* Is `12 > 6`? Yes.
* `credit = 12`
8. `width = width * 2` $\rightarrow$ `width = 6 * 2 = 12`
9. `width = width - 9` $\rightarrow$ `width = 12 - 9 = 3`
10. `credit = tally * 2` $\rightarrow$ `credit = 12 * 2 = 24`
11. `if width > credit:`
* Is `3 > 24`? No.
* Execute `else` block:
* `credit = width * 3` $\rightarrow$ `credit = 3 * 3 = 9`
* `credit = credit * 2` $\rightarrow$ `credit = 9 * 2 = 18`
12. `if width < 6:`
* Is `3 < 6`? Yes.
* Execute `if` block:
* `width -= tally` $\rightarrow$ `width = 3 - 12 = -9`
* `credit = tally + 4` $\rightarrow$ `credit = 12 + 4 = 16`
13. `width -= width` $\rightarrow$ `width = -9 - (-9) = 0`
14. `width -= width` $\rightarrow$ `width = 0 - 0 = 0`
Throughout the execution, the variable `tally` was modified only in steps 4 and 6.
* Initial: 4
* Step 4: 6
* Step 6: 12
No further operations modified `tally`.
