⚡️ Speed up method AlexNet._classify by 317%

Here’s an optimized version of your `AlexNet` class for improved speed and efficiency. The improvements include.

- Use list multiplication where possible, and avoid unnecessary use of `sum()` in loops.
- Use built-in functions efficiently.
- Precompute common values.



**Explanation of changes:**
- Replaced list comprehension with `[total_mod] * len(features)`, which is faster and more memory-efficient for filling a list with the same value.
- Only run `sum(features)` and modulo operation once, instead of for every element.
- Preserved the comments as instructed.
