Closes #62
What I changed
Added comprehensive edge cases to
problems/palindrome/cases.txt:a,Z).12321,12345).0P,1a2b3b2a1).No 'x' in Nixon,Was it a car or a cat I saw?).., !?).How it works
The problem statement requires checking if a string reads the same forwards and backwards after converting all uppercase letters to lowercase and removing all non-alphanumeric characters.
These additional test cases ensure that solutions across all supported languages (C, C++, JavaScript, and Python) properly handle single-character inputs, mixed digits, and symbols without failing boundary checks or character conversion.
Verification
Ran
python run.py palindromeacross all solution implementations:solution.c: passedsolution.cpp: passedsolution.js: passedsolution.py: passedSummary: 4 passed, 0 failed.
