Here is a short Python program.

```python
step = 9
depth = 9
extra = 2
if extra > step:
    depth -= 5
    step += extra
else:
    step += depth
    depth = extra if extra > depth else depth + 7
depth += 2
extra += extra
extra = depth if depth < extra else extra + 8
if step < extra:
    extra -= 8
nums = [0, 0]
parts = nums
parts += [14]
step += len(nums) + nums[-1]
if depth > extra:
    depth += extra
extra = extra * 3
depth = step if step < step else step + 4
depth = extra if extra > step else step + 5
```

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

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

1.  **Initial values:**
    `step = 9`
    `depth = 9`
    `extra = 2`

2.  **First `if/else` block:**
    `if extra > step:` (2 > 9) is **False**.
    Execute `else` block:
    `step += depth` $\rightarrow$ `step = 9 + 9 = 18`
    `depth = extra if extra > depth else depth + 7`
    Is `extra > depth` (2 > 9)? **False**.
    `depth = depth + 7` $\rightarrow$ `depth = 9 + 7 = 16`

3.  **Intermediate calculations:**
    `depth += 2` $\rightarrow$ `depth = 16 + 2 = 18`
    `extra += extra` $\rightarrow$ `extra = 2 + 2 = 4`
    `extra = depth if depth < extra else extra + 8`
    Is `depth < extra` (18 < 4)? **False**.
    `extra = extra + 8` $\rightarrow$ `extra = 4 + 8 = 12`

4.  **Second `if` block:**
    `if step < extra:` (18 < 12) is **False**.
    (No action taken).

5.  **List operations:**
    `nums = [0, 0]`
    `parts = nums` (Both point to the same list)
    `parts += [14]` $\rightarrow$ `nums` is now `[0, 0, 14]`
    `step += len(nums) + nums[-1]`
    `len(nums)` is 3.
    `nums[-1]` is 14.
    `step = 18 + 3 + 14 = 35`

6.  **Final blocks:**
    `if depth > extra:` (18 > 12) is **True**.
    `depth += extra` $\rightarrow$ `depth = 18 + 12 = 30`
    `extra = extra * 3` $\rightarrow$ `extra = 12 * 3 = 36`
    `depth = step if step < step else step + 4`
    Is `step < step` (35 < 35)? **False**.
    `depth = step + 4` $\rightarrow$ `depth = 35 + 4 = 39`
    `depth = extra if extra > step else step + 5`
    Is `extra > step` (36 > 35)? **True**.
    `depth = extra` $\rightarrow$ `depth = 36`

The question asks for the value of `step`. Looking back at the trace, the last time `step` was modified was during the list operation calculation.

`step = 35`
