Here is a Python function and one example where it returns the wrong value.

```python
def solve(peak, parts):
    bins = [9, 0]
    values = [2, 1, 3]
    parts.append(peak)
    if peak < peak:
        parts.append(peak)
    credit = peak + 3
    credit -= 4
    nums = [8, 3]
    cells = nums
    cells += [11]
    cells = cells + [20]
    items = nums[:]
    items.append(37)
    bins.append(len(nums) + nums[-1])
    stack = [5, 6, 7, 0, 2]
    tally = 0
    for elem in stack:
        if elem > peak:
            tally += elem
        else:
            tally += 3
    bins.append(tally)
    credit += peak
    scores = [5, 0, 7, 6, 1]
    codes = scores[1:len(scores) - 1]
    bins.append(len(codes) + codes[-1])
    bins.append(credit)
    bins.append(peak)
    bins.append(len(parts))
    bins.append(len(values))
    return bins
```

`solve(1, [5, 9, 9])` returns `[9, 0, 14, 23, 9, 1, 1, 4, 3]`, but it should return `[9, 0, 14, 17, 9, 1, 1, 4, 3]`.

Find and fix the bug. The fix will also be checked on other inputs. Return the corrected function, complete (with any helper functions it uses), in one ```python block. Keep the same name and parameters.

To fix the bug, we need to examine how the value `23` is calculated in the example `solve(1, [5, 9, 9])` and how it should become `17`.

Looking at the code:
1. `stack = [5, 6, 7, 0, 2]`
2. `tally = 0`
3. The loop iterates through `stack`. If `elem > peak`, `tally += elem`, otherwise `tally += 3`.
4. For `peak = 1`:
   - 5 > 1: tally = 5
   - 6 > 1: tally = 5 + 6 = 11
   - 7 > 1: tally = 11 + 7 = 18
   - 0 <= 1: tally = 18 + 3 = 21
   - 2 > 1: tally = 21 + 2 = 23
5. The result is `23`. To get `17`, we need to change the logic. If we change the `else` condition to add `0` instead of `3`, the calculation becomes `5 + 6 + 7 + 0 + 2 = 20`. If we change the `if` condition to `elem > 2` (or some other constant), it changes. However, looking at the difference $23 - 17 = 6$, it suggests that for `peak = 1`, the `else` block (which adds 3) was triggered twice, but it should have added 0, or the logic for adding `elem` was different.

Wait, if we change `tally += 3` to `tally += 0` (or simply remove it), the sum is $5+6+7+0+2 = 20$. Still not 17.
If we change the condition to `elem > peak + 1` (where peak=1, so `elem > 2`):
- 5 > 2: 5
- 6 > 2: 11
- 7 > 2: 18
- 0 <= 2: 18 + 3 = 21
- 2 <= 2: 21 + 3 = 24.

Let's re-evaluate: $5+6+7+0+2 = 20$. To get 17, we need to subtract 3.
If the logic was: `if elem > peak: tally += elem` and the `else` was `tally += 0`, but the `stack` was different? No, stack is constant.
If the logic was: `if elem > peak: tally += elem` but for `elem == 2` it didn't count?
Actually, if we change `tally += 3` to `tally += 0` and the loop only adds `elem` if `elem > peak`, then for `peak=1`: $5+6+7+2 = 20$.
If the logic is `if elem > peak + 1`: $5+6+7 = 18$.
If the logic is `if elem > peak` but we subtract 3 at the end? $23 - 3 = 20$.
Wait, if the `else` is `tally += 0` and the `if` is `elem > peak + 1`: $5+6+7 = 18$.
What if the `else` is `tally += 0` and the `if` is `elem > 2`? $5+6+7 = 18$.
What if the `if` is `elem > peak` and the `else` is `tally -= 3`?
- 5 > 1: 5
- 6 > 1: 11
- 7 > 1: 18
- 0 <= 1: 18 - 3 = 15
- 2 > 1: 15 + 2 = 17.

This matches! Let's check the logic: `if elem > peak: tally += elem else: tally -= 3`.

```python
def solve(peak, parts):
    bins = [9, 0]
    values = [2, 1, 3]
    parts.append(peak)
    if peak < peak:
        parts.append(peak)
    credit = peak + 3
    credit -= 4
    nums = [8, 3]
    cells = nums
    cells += [11]
    cells = cells + [20]
    items = nums[:]
    items.append(37)
    bins.append(len(nums) + nums[-1])
    stack = [5, 6, 7, 0, 2]
    tally = 0
    for elem in stack:
        if elem > peak:
            tally += elem
        else:
            tally -= 3
    bins.append(tally)
    credit += peak
    scores = [5, 0, 7, 6, 1]
    codes = scores[1:len(scores) - 1]
    bins.append(len(codes) + codes[-1])
    bins.append(credit)
    bins.append(peak)
    bins.append(len(parts))
    bins.append(len(values))
    return bins
```
