Here is a short Python program.

```python
cells = [5, 9]
depth = 1
peak = 6
peak = len(cells) // 4
cells.append(peak)
cells.append(depth * 2)
```

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

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

1.  `cells = [5, 9]`
    The list `cells` is initialized with two elements: `[5, 9]`.
2.  `depth = 1`
    The variable `depth` is assigned the value `1`.
3.  `peak = 6`
    The variable `peak` is assigned the value `6`.
4.  `peak = len(cells) // 4`
    *   `len(cells)` is `2` (since `cells` is `[5, 9]`).
    *   `2 // 4` is integer division, which equals `0`.
    *   `peak` is now `0`.
5.  `cells.append(peak)`
    *   The value of `peak` (`0`) is added to the end of the list.
    *   `cells` is now `[5, 9, 0]`.
6.  `cells.append(depth * 2)`
    *   `depth * 2` is `1 * 2`, which equals `2`.
    *   The value `2` is added to the end of the list.
    *   `cells` is now `[5, 9, 0, 2]`.

ANSWER: [5, 9, 0, 2]
