Here is a short Python program.

```python
cost = 5
queue = [2, 1]
delta = 1
if delta > 3:
    queue.extend([delta, 7])
else:
    cost += queue[-1]
cost += delta * 2  # cost changes .
delta = queue[0]
queue = queue[1:]  # queue changes ........
if delta == 8:
    queue = queue[1:]
    queue[0] = 0
```

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

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

1.  **Initialization:**
    *   `cost = 5`
    *   `queue = [2, 1]`
    *   `delta = 1`

2.  **First Conditional (`if delta > 3`):**
    *   `delta` is `1`.
    *   `1 > 3` is `False`.
    *   The `else` block executes: `cost += queue[-1]`.
    *   `queue[-1]` is the last element of `[2, 1]`, which is `1`.
    *   `cost = 5 + 1 = 6`.

3.  **Update `cost`:**
    *   `cost += delta * 2`
    *   `cost = 6 + (1 * 2) = 6 + 2 = 8`.

4.  **Update `delta` and `queue`:**
    *   `delta = queue[0]`
    *   `queue[0]` is `2`. So, `delta = 2`.
    *   `queue = queue[1:]`
    *   The slice of `[2, 1]` from index 1 onwards is `[1]`. So, `queue = [1]`.

5.  **Second Conditional (`if delta == 8`):**
    *   `delta` is `2`.
    *   `2 == 8` is `False`.
    *   The block inside the `if` statement is skipped.

6.  **Final State:**
    *   `cost = 8`
    *   `queue = [1]`
    *   `delta = 2`

The final value of `cost` is 8.
