Here is a short Python program.

```python
delta = 3
score = 7
stack = [9, 6]
score = len(stack) // 3
score = score * 3
score = len(stack) // 3
score = delta if delta > score else score + 8
score = stack[-1]
score = delta if delta > delta else delta + 9
stack.extend([0, 0])
delta += len(stack)

def shift_by(w, arg=2):
    return w * 2 - arg

stack = stack + [score]

def scale(amt, k=4):
    return amt * 2 + k

for e in stack:
    if e > 1:
        score = score if score < delta else delta + 8
    else:
        score = len(stack)
        score = stack[-1]
if score == 8:
    score = stack.pop()
    score = len(stack)
stack.append(score)
delta += score
score = score if score < delta else delta + 4
stack.extend([8, 0])
for cur in stack:
    score = score if score < delta else delta + 7
    score = delta if delta > score else score + 9
stack.extend([5, 2])
score = delta - 8
score = scale(delta, delta)
score = stack.pop()
score = score - 7
score = len(stack)
stack = stack[1:]
```

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

Let's trace the execution of the Python code step by step.

1. `delta = 3`
2. `score = 7`
3. `stack = [9, 6]`
4. `score = len(stack) // 3 = 2 // 3 = 0`
5. `score = score * 3 = 0 * 3 = 0`
6. `score = len(stack) // 3 = 2 // 3 = 0`
7. `score = delta if delta > score else score + 8 = 3 if 3 > 0 else 0 + 8 = 3`
8. `score = stack[-1] = 6`
9. `score = delta if delta > delta else delta + 9 = delta + 9 = 3 + 9 = 12`
10. `stack.extend([0, 0])`  `stack` becomes `[9, 6, 0, 0]`
11. `delta += len(stack) = delta + 4 = 3 + 4 = 7`

Now, let's look at the functions:

```python
def shift_by(w, arg=2):
    return w * 2 - arg

def scale(amt, k=4):
    return amt * 2 + k
```

12. `stack = stack + [score] = [9, 6, 0, 0] + [12] = [9, 6, 0, 0, 12]`
13. The `for` loop starts:
   - `e = 9`. `e > 1` is true. `score = score if score < delta else delta + 8 = score if 12 < 7 else 7 + 8 = 15`.
   - `e = 6`. `e > 1` is true. `score = score if score < delta else delta + 8 = score if 15 < 7 else 7 + 8 = 15`.
   - `e = 0`. `e > 1` is false. `score = len(stack) = 5`. `score = stack[-1] = 12`.
   - `e = 0`. `e > 1` is false. `score = len(stack) = 5`. `score = stack[-1] = 12`.
   - `e = 12`. `e > 1` is true. `score = score if score < delta else delta + 8 = score if 12 < 7 else 7 + 8 = 15`.
14. `if score == 8`: `15 == 8` is false.
15. `stack.append(score)`: `stack.append(15)`  `stack` becomes `[9, 6, 0, 0, 12, 15]`
16. `delta += score = delta + 15 = 7 + 15 = 22`
17. `score = score if score < delta else delta + 4 = score if 15 < 22 else 22 + 4 = 15`
18. `stack.extend([8, 0])`  `stack` becomes `[9, 6, 0, 0, 12, 15, 8, 0]`
19. The `for` loop starts:
   - `cur = 9`. `score = score if score < delta else delta + 7 = score if 15 < 22 else 22 + 7 = 29`. `score = delta if delta > score else score + 9 = 22 if 22 > 29 else 29 + 9 = 38`.
   - `cur = 6`. `score = score if score < delta else delta + 7 = score if 38 < 22 else 22 + 7 = 38`. `score = delta if delta > score else score + 9 = 22 if 22 > 38 else 38 + 9 = 47`.
   - `cur = 0`. `score = score if score < delta else delta + 7 = score if 47 < 22 else 22 + 7 = 47`. `score = delta if delta > score else score + 9 = 22 if 22 > 47 else 47 + 9 = 56`.
   - `cur = 0`. `score = score if score < delta else delta + 7 = score if 56 < 22 else 22 + 7 = 56`. `score = delta if delta > score else score + 9 = 22 if 22 > 56 else 56 + 9 = 65`.
   - `cur = 12`. `score = score if score < delta else delta + 7 = score if 65 < 22 else 22 + 7 = 65`. `score = delta if delta > score else score + 9 = 22 if 22 > 65 else 65 + 9 = 74`.
   - `cur = 15`. `score = score if score < delta else delta + 7 = score if 74 < 22 else 22 + 7 = 74`. `score = delta if delta > score else score + 9 = 22 if 22 > 74 else 74 + 9 = 83`.
   - `cur = 8`. `score = score if score < delta else delta + 7 = score if 83 < 22 else 22 + 7 = 83`. `score = delta if delta > score else score + 9 = 22 if 22 > 83 else 83 + 9 = 92`.
   - `cur = 0`. `score = score if score < delta else delta + 7 = score if 92 < 22 else 22 + 7 = 92`. `score = delta if delta > score else score + 9 = 22 if 22 > 92 else 92 + 9 = 101`.
20. `stack.extend([5, 2])`  `stack` becomes `[9, 6, 0, 0, 12, 15, 8, 0, 5, 2]`
21. `score = delta - 8 = 22 - 8 = 14`
22. `score = scale(delta, delta) = scale(22, 22) = 22 * 2 + 22 = 44 + 22 = 66`
23. `score = stack.pop() = 2`  `stack` becomes `[9, 6, 0, 0, 12, 15, 8, 0, 5]`
24. `score = score - 7 = 2 - 7 = -5`
25. `score = len(stack) = 9`
26. `stack = stack[1:] = [6, 0, 0, 12, 15, 8, 0, 5]`

The final value of `delta` is 22.
