Here is a short Python program.

```python
nums = [7, 7, 2, 7]
step = 2
rows = [4, 7, 7]
if step == step:
    step = len(rows)
else:
    rows[-1] = step
if step == 2:
    rows.append(8)
    nums.append(len(rows))
else:
    nums.append(step * 2)
    nums.append(step * 2)
if step < step:
    rows = rows[1:]
    step = rows.pop()
step = step if step < step else step + 9
for cur in nums:
    step = step * 3
step = step if step > step else step + 5
rows = nums[1:]
for entry in nums:
    step -= entry
rows = nums[1:]
```

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, 7, 2, 7]`
    `step = 2`
    `rows = [4, 7, 7]`

2.  **First `if` block:**
    `if step == step:` (2 == 2 is True)
    `step = len(rows)` $\rightarrow$ `step = 3` (since `rows` has 3 elements)

3.  **Second `if` block:**
    `if step == 2:` (3 == 2 is False)
    `else:`
    `nums.append(step * 2)` $\rightarrow$ `nums.append(6)` $\rightarrow$ `nums = [7, 7, 2, 7, 6]`
    `nums.append(step * 2)` $\rightarrow$ `nums.append(6)` $\rightarrow$ `nums = [7, 7, 2, 7, 6, 6]`

4.  **Third `if` block:**
    `if step < step:` (3 < 3 is False)
    (The block is skipped)

5.  **Ternary operation for `step`:**
    `step = step if step < step else step + 9`
    Since `3 < 3` is False, `step = 3 + 9 = 12`.

6.  **First `for` loop:**
    `for cur in nums:`
    `nums` is `[7, 7, 2, 7, 6, 6]` (6 elements).
    The loop runs 6 times, multiplying `step` by 3 each time.
    `step = 12 * (3**6) = 12 * 729 = 8748`.

7.  **Ternary operation for `step`:**
    `step = step if step > step else step + 5`
    Since `8748 > 8748` is False, `step = 8748 + 5 = 8753`.

8.  **Final operations:**
    `rows = nums[1:]` $\rightarrow$ `rows = [7, 2, 7, 6, 6]`
    `for entry in nums:`
    `step -= entry` (This modifies `step`, but not `nums`)
    `rows = nums[1:]` $\rightarrow$ `rows = [7, 2, 7, 6, 6]`

Throughout the latter half of the program, the variable `nums` is never modified again. The modifications were only to `step` and `rows`.

The final state of `nums` is `[7, 7, 2, 7, 6, 6]`.
