Paulami Bhosle — R23-T052: Add a variant next to conversions/rgb_cmyk_conversion.py #52

Student: Paulami Bhosle

Task: R23-T052 · 2 of 10
Repository: https://github.com/S-AI-Projects/TheAlgorithms-Python
Assigned working branch: student/e26b07f0792

Goal

Contribute a new file in conversions/ that follows every repository rule. Add cmyk_to_rgb as a new file and check the round trip rgb → cmyk → rgb (allowing for rounding).

Steps

1. Read CONTRIBUTING.md: snake_case file names, type hints, doctests for valid and erroneous input, no new directories.
2. Create the new file in conversions/ as described in the goal, with doctests that also compare against the existing implementation.
3. Run python3 scripts/validate_filenames.py, Ruff and the doctests.
4. Explain in work/R23-T052/VARIANT.md how your version differs (time/space), with a small timing table.
5. Make the code change in the repository: New conversions/cmyk_to_rgb.py (inverse conversion) with doctests including a round trip with rgb_cmyk_conversion.py. Re-run the automated check and the repo's own tests afterwards.
6. Prepare the PR: on branch R23-T052, commit the code change plus your work/R23-T052/ evidence, put your findings in the PR description and open the PR against the org fork. For a later upstream PR, create a second branch containing only the code change (no work/ folder).

Done when

☐ New conversions/cmyk_to_rgb.py with type hints, validation (ValueError for out-of-range input) and doctests.
☐ A doctest round-trips rgb → cmyk (via rgb_cmyk_conversion.rgb_to_cmyk) → rgb within ±1 per channel.
☐ validate_filenames.py and Ruff pass; VARIANT.md explains the rounding.
