Common mistakes include misreading the problem, overlooking edge cases, and ignoring constraints. Practice and careful analysis help reduce these errors.

Competitive programming can be error-prone, especially under time pressure. Common mistakes include misinterpreting problem requirements, overlooking edge cases, or failing to account for input constraints. To avoid these, it’s essential to read the problem statement thoroughly and make note of any specific requirements or constraints. Testing solutions against edge cases helps catch errors early, while analyzing time complexity ensures the solution runs within time limits. Keeping a calm mindset and checking for common pitfalls, like off-by-one errors in loops or unintended integer overflow, further minimizes mistakes. Consistent practice, combined with careful analysis, helps competitive programmers improve their accuracy and avoid common errors in contests.
