Here is a short Python program.

```python
def pack(num, val=5):
    return num * 2 - val

def solve(width, parts):
    height = 3
    spare = 1
    value = height + 3
    value = value // 2
    cells = [6, 1]
    queue = cells
    queue += [13]
    queue = queue + [21]
    items = cells[:]
    items.append(36)
    width += len(cells) + cells[-1]
    batch = [5, 9, 3, 7]
    margin = 0
    for elem in batch:
        if elem > height:
            margin += elem
        else:
            margin -= 3
    width += margin
    value += spare
    rows = [4, 0, 1, 5, 3]
    bins = rows[1:len(rows) - 1 - 1]
    width += len(bins) + bins[-1]
    width += value
    width += height * 2
    width += len(parts)
    width += spare
    return width
```

What does `solve(3, [9, 1, 3])` return? Work through it carefully, then give the final answer on its own last line as `ANSWER: <python literal>`.

To find the return value of `solve(3, [9, 1, 3])`, let's step through the function execution with the given arguments: `width = 3` and `parts = [9, 1, 3]`.

1.  **Initial variables:**
    *   `width = 3`
    *   `parts = [9, 1, 3]`
    *   `height = 3`
    *   `spare = 1`
    *   `value = height + 3` $\rightarrow$ `3 + 3 = 6`
    *   `value = value // 2` $\rightarrow$ `6 // 2 = 3`

2.  **List operations:**
    *   `cells = [6, 1]`
    *   `queue = cells` (Reference to `[6, 1]`)
    *   `queue += [13]` $\rightarrow$ `queue` and `cells` are now `[6, 1, 13]`
    *   `queue = queue + [21]` $\rightarrow$ `queue` is now `[6, 1, 13, 21]`, but `cells` remains `[6, 1, 13]`
    *   `items = cells[:]` $\rightarrow$ `items = [6, 1, 13]`
    *   `items.append(36)` $\rightarrow$ `items = [6, 1, 13, 36]`

3.  **Updating `width` (First step):**
    *   `width += len(cells) + cells[-1]`
    *   `len(cells)` is 3. `cells[-1]` is 13.
    *   `width = 3 + 3 + 13 = 19`

4.  **Calculating `margin`:**
    *   `batch = [5, 9, 3, 7]`
    *   `margin = 0`
    *   Loop through `batch`:
        *   `elem = 5`: `5 > 3` is True $\rightarrow$ `margin = 0 + 5 = 5`
        *   `elem = 9`: `9 > 3` is True $\rightarrow$ `margin = 5 + 9 = 14`
        *   `elem = 3`: `3 > 3` is False $\rightarrow$ `margin = 14 - 3 = 11`
        *   `elem = 7`: `7 > 3` is True $\rightarrow$ `margin = 11 + 7 = 18`
    *   `width += margin` $\rightarrow$ `19 + 18 = 37`

5.  **Updating `value`:**
    *   `value += spare` $\rightarrow$ `3 + 1 = 4`

6.  **Calculating `bins` and updating `width`:**
    *   `rows = [4, 0, 1, 5, 3]`
    *   `bins = rows[1 : len(rows) - 1 - 1]` $\rightarrow$ `rows[1 : 5 - 2]` $\rightarrow$ `rows[1 : 3]`
    *   `bins = [0, 1]`
    *   `width += len(bins) + bins[-1]`
    *   `len(bins)` is 2. `bins[-1]` is 1.
    *   `width = 37 + 2 + 1 = 40`

7.  **Final `width` additions:**
    *   `width += value` $\rightarrow$ `40 + 4 = 44`
    *   `width += height * 2` $\rightarrow$ `44 + (3 * 2) = 44 + 6 = 50`
    *   `width += len(parts)` $\rightarrow$ `50 + 3 = 53`
    *   `width += spare` $\rightarrow$ `53 + 1 = 54`
