Here is a short Python program.

```python
queue = [3, 3, 6]
nums = [0, 6]
tally = 7
queue.append(nums[-1])
for cur in nums:
    tally += cur
    tally = len(queue) // 3
scores = queue
scores[0] = 17
if tally < 2:
    nums.append(6)
    tally = len(queue) % 2
else:
    tally = tally if tally > tally else tally + 2
    queue.append(tally)
shift = 5

def scale(arg):
    return arg * shift

shift += 5
queue.append(scale(2))

def pack(n):
    tally = n * 2 + 1
    return tally + 1

weight = pack(7)
queue.append(tally + weight)
for j in range(3):
    queue.append(j)
total = tally - 2
margin = total % 6
queue.append(margin)

def collect(acc, k=[]):
    k.append(acc)
    return len(k)

count = collect(3)
score = collect(8)
queue.append(count + score)
```

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

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

1.  **Initialization:**
    `queue = [3, 3, 6]`
    `nums = [0, 6]`
    `tally = 7`

2.  **First operations:**
    `queue.append(nums[-1])` $\rightarrow$ `nums[-1]` is 6. `queue` becomes `[3, 3, 6, 6]`.

3.  **The first loop:**
    `for cur in nums:` (nums is `[0, 6]`)
    - Iteration 1 (`cur = 0`):
        `tally += 0` (tally is 7)
        `tally = len(queue) // 3` $\rightarrow$ `4 // 3 = 1`. `tally` is now 1.
    - Iteration 2 (`cur = 6`):
        `tally += 6` (tally is $1 + 6 = 7$)
        `tally = len(queue) // 3` $\rightarrow$ `4 // 3 = 1`. `tally` is now 1.

4.  **Scores and Conditionals:**
    `scores = queue` (Both variables now point to the same list object).
    `scores[0] = 17` $\rightarrow$ `queue` becomes `[17, 3, 6, 6]`.
    `if tally < 2:` (tally is 1, so this is True).
    `nums.append(6)` $\rightarrow$ `nums` is `[0, 6, 6]`.
    `tally = len(queue) % 2` $\rightarrow$ `4 % 2 = 0`. `tally` is now 0.

5.  **Scaling and Appending:**
    `shift = 5`
    `def scale(arg): return arg * shift`
    `shift += 5` $\rightarrow$ `shift` is now 10.
    `queue.append(scale(2))` $\rightarrow$ `scale(2)` is $2 \times 10 = 20$. `queue` becomes `[17, 3, 6, 6, 20]`.

6.  **Packing and Weight:**
    `def pack(n): tally = n * 2 + 1; return tally + 1`
    `weight = pack(7)` $\rightarrow$ $(7 \times 2 + 1) + 1 = 16$. `weight` is 16.
    `queue.append(tally + weight)` $\rightarrow$ `tally` is 0, `weight` is 16. $0 + 16 = 16$. `queue` becomes `[17, 3, 6, 6, 20, 16]`.

7.  **The second loop:**
    `for j in range(3): queue.append(j)`
    `queue` becomes `[17, 3, 6, 6, 20, 16, 0, 1, 2]`.

8.  **Margin calculation:**
    `total = tally - 2` $\rightarrow$ $0 - 2 = -2$.
    `margin = total % 6` $\rightarrow$ $-2 \pmod 6 = 4$.
    `queue.append(margin)` $\rightarrow$ `queue` becomes `[17, 3, 6, 6, 20, 16, 0, 1, 2, 4]`.

9.  **Collect function (Mutable Default Argument):**
    `def collect(acc, k=[]): k.append(acc); return len(k)`
    - `count = collect(3)` $\rightarrow$ `k` becomes `[3]`, returns 1. `count = 1`.
    - `score = collect(8)` $\rightarrow$ `k` (the same list) becomes `[3, 8]`, returns 2. `score = 2`.
    `queue.append(count + score)` $\rightarrow$ $1 + 2 = 3$. `queue` becomes `[17, 3, 6, 6, 20, 16, 0, 1, 2, 4, 3]`.
