Here is a short Python program.

```python
queue = [1, 0]
extra = 6
tally = 4
queue.append(tally)
queue.append(extra)
extra = queue[0]
```

After this program runs, what is the value of `queue`? Work through it carefully, then give the final answer on its own last line as `ANSWER: <python literal>`.
Response 306 tokens out · finish: stop
To determine the final value of `queue`, let's trace the program step-by-step:

1.  `queue = [1, 0]`
    The list `queue` is initialized as `[1, 0]`.
2.  `extra = 6`
    The variable `extra` is assigned the value `6`.
3.  `tally = 4`
    The variable `tally` is assigned the value `4`.
4.  `queue.append(tally)`
    The value of `tally` (4) is added to the end of the list.
    `queue` is now `[1, 0, 4]`.
5.  `queue.append(extra)`
    The value of `extra` (6) is added to the end of the list.
    `queue` is now `[1, 0, 4, 6]`.
6.  `extra = queue[0]`
    The value at index 0 of `queue` (which is 1) is assigned to the variable `extra`.
    This changes the value of `extra` to 1, but it does not modify the `queue` list.

The final state of `queue` is `[1, 0, 4, 6]`.
