📝 Walkthrough

Walkthrough

This PR adds a LeetCode solution for the Group Anagrams problem (LeetCode 49) using sorted-character-based dictionary grouping, along with parametrized tests covering multiple test cases. The PR also cleans up a now-orphaned test that depended on deleted module code.

Changes

LeetCode Group Anagrams Solution and Tests

Layer / File(s)	Summary
Group Anagrams solution implementation LeetCode/medium/group_anagrams_49.py	Introduces Solution.groupAnagrams method that groups strings by their sorted-character keys, building a dictionary and returning the grouped lists.
Group Anagrams tests and cleanup tests/test_leetcode_medium.py, tests/test_leetcode.py	Adds parametrized test_group_anagram in test_leetcode_medium.py with multiple test cases and order-insensitive comparison. Removes test_maxSlidingWindow from test_leetcode.py due to its source module deletion.

Poem

🐰 Anagrams dance in sorted rows,
Where "eat" and "tea" together close,
The dictionary holds them true,
A medium problem solved anew!

🚥 Pre-merge checks | ✅ 3 | ❌ 2

❌ Failed checks (2 warnings)

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The title references 'group anagrams', which is addressed by the LeetCode solution addition, but the PR also removes extensive code from 6 files; the title fails to reflect this significant deletion activity.	Revise the title to acknowledge the substantial deletions, such as 'refactor: clean up code and add group anagrams solution' or 'chore: remove old implementations and add LeetCode group anagrams solution'.
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
