Summary

This PR adds a new function scale_list under the bit_manipulation/ folder.

What It Does

• The scale_list function takes a list of numbers and a scaling factor, and returns a new list with each element multiplied by the factor.
• Includes a unit test file test_scale_list.py to verify correctness.

Why It's Useful

This provides a simple mathematical utility for scaling lists — useful in data preprocessing and basic arithmetic operations.

Notes

• All code follows PEP8 style.
• All tests pass using unittest.
