* Fix `RuntimeError` in bipartite-check DFS/BFS and clean up doctests
* Iteration over `graph` mutated by `defaultdict` neighbours caused
`RuntimeError: dictionary changed size during iteration`.
– Iterate over `list(graph)` in both DFS and BFS helpers.
* Corrected `if __name__ == "__main__":` typo.
* Updated two doctests that now succeed after the fix.
All doctests now pass (`30/30`), eliminating a critical runtime failure and improving reliability of the graph algorithms.

* fix(strings): use frequency-based signature for anagrams
Replaced the sorting-based signature implementation with a frequency-based
approach using `collections.Counter`. This ensures that the signature
represents both characters and their counts, preventing collisions and
better grouping of true anagrams.
Examples:
- "test" → "e1s1t2"
- "finaltest" → "a1e1f1i1l1n1s1t2"
- "this is a test" → " 3a1e1h1i2s3t3"
Also updated the anagram lookup to use the new frequency-based signatures, making results more accurate and avoiding false positives.
* Refactor anagram function return type to list[str]
* Update anagrams.py
* Update anagrams.py
* Update anagrams.py
* Update anagrams.py

* Update .pre-commit-config.yaml to reflect current linting and formatting setup
- Replaced outdated references to `black` with the actual tools used in the repo: `ruff` and `ruff-format`.
- Ensured all configured hooks are up to date and relevant to Python development.
- This aligns the linting and formatting setup with the project's actual pre-commit pipeline.
- Improves consistency for contributors by preventing confusion between formatting tools.
