Here is a short Python program.

```python
nums = [7, 9]
bins = [0, 2, 7, 9]
values = [2, 7]
nums.append(len(values))
values = values + [4]
nums.append(len(bins))
```

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

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

1.  **Initialization:**
    *   `nums = [7, 9]`
    *   `bins = [0, 2, 7, 9]`
    *   `values = [2, 7]`

2.  **First operation: `nums.append(len(values))`**
    *   `len(values)` is `2` (since `values` is `[2, 7]`).
    *   `nums` becomes `[7, 9, 2]`.

3.  **Second operation: `values = values + [4]`**
    *   `values` becomes `[2, 7, 4]`.
    *   (Note: This does not affect `nums` at this moment).

4.  **Third operation: `nums.append(len(bins))`**
    *   `len(bins)` is `4` (since `bins` is `[0, 2, 7, 9]`).
    *   `nums` becomes `[7, 9, 2, 4]`.

Final state of `nums`: `[7, 9, 2, 4]`

ANSWER: [7, 9, 2, 4]
