Logic errors occur when your algorithm does not correctly implement the problem's requirements. These errors often stem from misunderstanding the problem or missing small but crucial details. To fix logic errors, go back to the problem statement and carefully read through each constraint and example. Compare your solution's logic to what the problem is asking for. Additionally, walk through your code with sample inputs to see if it behaves as expected. Writing pseudocode or breaking the problem into smaller pieces can help clarify the logic. Pay attention to edge cases or special conditions that your solution might not handle correctly. Correcting the core logic of your algorithm is the most effective way to solve these types of errors.
