How I Improved My Problem-Solving Skills on Codeforces

When I started competitive programming on Codeforces, I found it hard to keep up with the speed of contests. Over time, I learned strategies that helped me get better. Here’s a quick summary of what worked for me:

1. Master the Basics

• Learned important algorithms like binary search and sorting.
• Practiced simple data structures like arrays and hash maps.
• Solved problems rated 800-1200 to build confidence and improve speed.

2. Practice with Focus

• Worked on weak topics (e.g., greedy, bitmasks) and solved harder problems step by step.
• Used Codeforces’ "tags" to find problems on specific topics.
• After contests, solved the problems I couldn’t complete during the competition.

3. Participate in Contests Regularly

• Focused on solving the easiest problems first to avoid mistakes.
• Took part in virtual contests to practice working under time pressure.
• Studied editorial solutions and wrote the code to learn better methods.

4. Learn from Mistakes

• Kept a list of common mistakes, like missing edge cases or coding errors.
• Checked my solutions to make them simpler and faster.
• Asked questions in the discussion section when I didn’t understand something.

5. Be Consistent

• Set small goals, like solving a few problems every week.
• Followed experienced users and studied their solutions to learn new ideas.
• Celebrated achievements, like reaching a higher rating or solving a difficult problem.

Improving on Codeforces takes time and effort, but every problem you solve helps you move forward. Stay consistent, take on challenges, and you’ll see progress. Share your tips and experiences in the comments—I’d love to hear how you’re doing!
