Debugging is an essential skill in competitive programming, and improving it involves developing a methodical approach to finding errors. Start by breaking down your code into smaller, testable parts, and use print statements or debugging tools to track the flow of data and identify where the problem occurs. Testing your code on edge cases and comparing expected and actual results is also crucial. Analyzing the problem constraints carefully can help you spot issues before they become bugs. With practice, you’ll get better at quickly identifying and fixing errors, which will save valuable time during contests.
