To review code effectively, revisit each solution, test with edge cases, and compare your approach to other solutions to find improvements.

Reviewing your own code post-contest is essential for growth in competitive programming. Start by revisiting each problem and thoroughly examining your solution line by line to ensure it’s logically sound. Testing your code with edge cases or alternative inputs helps identify potential oversights or inefficiencies you might have missed during the contest. Comparing your approach with other top solutions can reveal faster or more elegant methods, as well as highlight any unnecessary complexity in your code. Analyzing your code for readability and structure is also valuable, as clear code makes debugging easier and prepares you for future adjustments. Reflecting on any points where you got stuck or made errors helps you understand the root causes, such as knowledge gaps or hasty decisions, so you can address them in future practice. Regular code review enhances your ability to write optimized and reliable code in future contests.
