Here is a short Python program.

```python
size = 4
step = 2
title = 'kit'
title = title[1:]
step = size * 2
batch = [3, 1]
values = batch
values[0] = 17
size += batch[0]
shift = 2

def shift_by(v):
    return v + shift

shift = 5
size += shift_by(3)

def pack(w):
    step = w * 2 + 1
    return step + 1

total = pack(4)
size += step + total
for idx in range(6):
    size += idx * 3
spare = step - 10
limit = spare % 4
size += limit

def grow(val, n=[]):
    n.append(val)
    return len(n) + val

weight = grow(3)
value = grow(3)
size += weight + value
size += step
size += len(title)
```

After this program runs, what is the value of `size`? 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 to determine the final value of `size`.

1. `size = 4`
2. `step = 2`
3. `title = 'kit'`
4. `title = title[1:]`  # title becomes 'it'
5. `step = size * 2`  # step = 4 * 2 = 8
6. `batch = [3, 1]`
7. `values = batch`  # values now refers to the same list as batch
8. `values[0] = 17`  # batch[0] is also modified, so batch becomes [17, 1]
9. `size += batch[0]`  # size = 4 + 17 = 21
10. `shift = 2`
11. `def shift_by(v): ...`
12. `shift = 5`
13. `size += shift_by(3)`  # size = 21 + (3 + 5) = 21 + 8 = 29
14. `def pack(w): ...`
15. `total = pack(4)`  # total = (4 * 2 + 1) + 1 = 8 + 1 + 1 = 10
16. `size += step + total`  # size = 29 + 8 + 10 = 47
17. `for idx in range(6): ...`
   - `idx = 0`: `size += 0 * 3`  # size = 47
   - `idx = 1`: `size += 1 * 3`  # size = 47 + 3 = 50
   - `idx = 2`: `size += 2 * 3`  # size = 50 + 6 = 56
   - `idx = 3`: `size += 3 * 3`  # size = 56 + 9 = 65
   - `idx = 4`: `size += 4 * 3`  # size = 65 + 12 = 77
   - `idx = 5`: `size += 5 * 3`  # size = 77 + 15 = 92
18. `spare = step - 10`  # spare = 8 - 10 = -2
19. `limit = spare % 4`  # limit = -2 % 4 = 2
20. `size += limit`  # size = 92 + 2 = 94
21. `def grow(val, n=[]): ...`
22. `weight = grow(3)`  # grow(3) returns 1 + 3 = 4, weight = 4
23. `value = grow(3)`  # grow(3) returns 1 + 3 = 4, value = 4
24. `size += weight + value`  # size = 94 + 4 + 4 = 102
25. `size += step`  # size = 102 + 8 = 110
26. `size += len(title)`  # size = 110 + 2 = 112

ANSWER: 112
