About

Welcome to the ACM CESA Debugging Challenge — a rigorous test of your coding insight and problem-solving prowess! In this contest, you’ll dive into expertly crafted code snippets spanning C++, Java, and Python, each laced with subtle bugs designed to challenge even the sharpest developers.

Your mission is to identify and understand these hidden errors that cause unexpected behavior, logical flaws, or runtime issues. This is not just about writing code — it’s about thinking critically, analyzing complex logic, and mastering the art of debugging in real-world scenarios.

Whether you’re a seasoned coder or an aspiring software engineer, this challenge will push your skills to the limit and prepare you for the coding problems. Sharpen your eyes, trust your instincts, and prove your mastery in the art of bug hunting!

Scoring

  • Each challenge has a pre-determined score.
  • A participant’s score depends on the number of test cases a participant’s code submission successfully passes.
  • If a participant submits more than one solution per challenge, then the participant’s score will reflect the highest score achieved. In a game challenge, the participant's score will reflect the last code submission.
  • Participants are ranked by score. If two or more participants achieve the same score, then the tie is broken by the total time taken to submit the last solution resulting in a higher score
