Debugging is crucial in competitive programming, as errors can prevent even correct logic from producing the expected results. To improve debugging skills, start with simple print statements to check variable values at various stages of the program, helping identify where logic diverges from expectations. Additionally, learn to mentally trace the flow of the code line by line, simulating inputs and outputs to ensure you understand each operation. Many coding environments provide built-in debugging tools that allow you to set breakpoints, step through code, and monitor variable changes, which can be invaluable for identifying issues. Practicing debugging in small, isolated code snippets or solving smaller test cases before moving to full solutions also helps build intuition. Regular debugging practice will enhance your ability to quickly identify and fix errors, saving valuable time during contests.
