Here is a short Python program.

```python
scores = [1, 7, 8]
items = [3, 6, 7]
step = 4
scores_ = [3, 2, 2]
scores.append(step * 2)
scores_ = scores_ + [step]
for elem in scores:
    step = step * 2
step = len(scores) % 4
for cur in scores:
    step -= cur
    step = len(scores_) // 4
scores.append(len(items))
scores_[0] = step
items = items + [step]
step -= step
scores_.append(step)
scores_.append(len(items))
```

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

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

1.  **Initialization:**
    *   `scores = [1, 7, 8]`
    *   `items = [3, 6, 7]`
    *   `step = 4`
    *   `scores_ = [3, 2, 2]`

2.  **Operations:**
    *   `scores.append(step * 2)`: `step * 2` is $4 \times 2 = 8$.
        `scores` becomes `[1, 7, 8, 8]`.
    *   `scores_ = scores_ + [step]`: `scores_` becomes `[3, 2, 2, 4]`.
    *   `for elem in scores: step = step * 2`:
        The loop runs 4 times (length of `scores`).
        - Iteration 1: `step = 4 * 2 = 8`
        - Iteration 2: `step = 8 * 2 = 16`
        - Iteration 3: `step = 16 * 2 = 32`
        - Iteration 4: `step = 32 * 2 = 64`
        `step` is now `64`.
    *   `step = len(scores) % 4`: `len(scores)` is 4. $4 \pmod 4 = 0$.
        `step` is now `0`.
    *   `for cur in scores: step -= cur; step = len(scores_) // 4`:
        The loop runs 4 times.
        - Iteration 1: `step = 0 - 1 = -1`; then `step = 4 // 4 = 1`.
        - Iteration 2: `step = 1 - 7 = -6`; then `step = 4 // 4 = 1`.
        - Iteration 3: `step = 1 - 8 = -7`; then `step = 4 // 4 = 1`.
        - Iteration 4: `step = 1 - 8 = -7`; then `step = 4 // 4 = 1`.
        `step` is now `1`.
    *   `scores.append(len(items))`: `len(items)` is 3.
        `scores` becomes `[1, 7, 8, 8, 3]`.
    *   `scores_[0] = step`: `scores_[0]` becomes `1`.
        `scores_` is now `[1, 2, 2, 4]`.
    *   `items = items + [step]`: `items` becomes `[3, 6, 7, 1]`.
    *   `step -= step`: `step` becomes `0`.
    *   `scores_.append(step)`: `scores_` becomes `[1, 2, 2, 4, 0]`.
    *   `scores_.append(len(items))`: `len(items)` is 4.
        `scores_` becomes `[1, 2, 2, 4, 0, 4]`.

3.  **Final Value of `scores`:**
    Looking back at the operations, `scores` was modified at:
    - `scores.append(step * 2)` $\rightarrow$ `[1, 7, 8, 8]`
    - `scores.append(len(items))` $\rightarrow$ `[1, 7, 8, 8, 3]`

ANSWER: [1, 7, 8, 8, 3]
