Codeforces - DJC
Codeforces is one of the world's most popular platforms for practicing competitive programming. It was created with the goal of bringing together programmers of different skill levels to solve algorithmic problems, learn new techniques, and improve logical thinking and optimization skills.
What is Codeforces?
Codeforces is a website that organizes online programming contests and offers a large collection of problems covering topics such as:
- Algorithms and data structures.
- Object-oriented programming.
- Mathematics applied to computer science.
- Optimization and complexity analysis.
Every user can register for free, participate in contests, and practice individually to level up.
What is it used for?
- Regular competitions: Codeforces organizes weekly contests (such as Div. 2, Div. 3, and Div. 4), where participants compete by solving several problems within a limited time.
- Personal training: Its extensive problem repository allows you to practice at your own pace.
- Measuring skill level: It has a rating system, similar to chess, that indicates your progress and classifies you by color, from Newbie to Legendary Grandmaster.
Why is it useful for our learning?
- Improves algorithmic thinking: Solving problems forces you to design efficient solutions.
- You learn new techniques: By reviewing other users' solutions after each contest, you discover different approaches and optimizations.
- Strengthens speed and accuracy: Ideal for training under pressure, such as in technical interviews or competitions.
- Builds discipline: Regular participation develops consistency and motivation.
