pmpp_v2/histogram_py: task.yml description does not match reference.py implementation

[pedrozoivan627-web]

Hi, thanks for maintaining this repository and the PMPP practice problems.

I noticed a mismatch in problems/pmpp_v2/histogram_py between the task description and the actual implementation.

In task.yml, the description says:

• the minimum and maximum values are fixed to 0 and 100
• all sizes are multiples of 16
• the number of bins is size / 16

However, in reference.py and submission.py, the implementation appears to use:

• input values in the range [0, 255]
• a fixed output size of 256 bins
• torch.bincount(..., minlength=256)

So it seems the current evaluation behavior is based on 256 fixed bins, not size / 16.

Would you mind confirming which behavior is intended?
If helpful, I can also open a PR to update the description for consistency.

Thanks again for the great project.
