   Hi @gaogaotiantian,
   
   Thank you for your candid feedback and for pointing out the issue with 
implicit casting. 
   
   To be completely transparent, as students working on this, we did use an LLM 
helper to help us analyze the codebase and interpret the existing TODO comment. 
However, we now realize that the generated logic was too naive, strictly 
focused on the TODO text, and completely overlooked PySpark's implicit casting 
behaviors (like bool vs int) which, as you correctly noted, introduces 
regressions. We sincerely apologize for pushing code that didn't meet the 
project's quality standards.
   
   This is a critical assignment for our university lab, and our grade heavily 
depends on getting this PR properly reviewed and progressing towards an 
accepted state. We are fully committed to fixing this and doing it the right 
way. 
   
   Could you please give us a hint or guide us on how we should properly handle 
this comparison? If you could point us in the right direction, we will 
completely rewrite the implementation and update the PR immediately to match 
the expected Pandas/PySpark behavior. 
   
   Thank you so much for your patience and mentorship!
