Wrong answers are often due to edge cases or incorrect logic. Try testing your code with custom test cases and reviewing your algorithm.

Wrong answers (WAs) in competitive programming usually stem from either failing to account for edge cases or incorrect logic in your solution. To debug a wrong answer, start by carefully reading the problem statement again to ensure you understand all the constraints. Then, create custom test cases, especially for edge cases like empty inputs, the largest or smallest values, and unique situations. Use print statements to trace the execution flow and variables at different stages of your code. Compare your approach with the expected solution, and check if you're handling all cases correctly. Using a systematic debugging approach will help you identify and fix the root cause of wrong answers in your competitive programming solutions.
