Why is everyone using CodeChef instead of Codeforces?

This is what I have observed regarding participation in codechef and codeforces.

Suppose you are a beginner and want to solve problems in the data structure and algorithms.

• Codechef organizes a long programming competition that lasts 10 days.
• Since this programming contest lasts 10 days, it becomes friendly for beginners.
• If you are a beginner and only know the basics of the language, then you could also participate in these contests.
• Suppose you participated in a long programming contest and don't know the underlying concept of data structure and algorithms for a particular question. So you could learn about that Data Structure and Algorithm and practice some questions and then try to solve a particular question.
• People keep repeating the previous step to the point where they are familiar with all the concepts of DS and Algorithms.

They don't just get familiar with the concepts of DS and ALGORITHMS by practicing there.

• They also start to like the codechef environment and are comfortable with the long programming contest.
• They began to enjoy the long programming contest and the participants formed a habit of solving problems by doing research on the topic and concepts.
• Once they start practicing more on the codechef website, their ranking in the programming contest starts to improve.
• Now people start to fall into the ranking and contest rankings they have on the codechef website.

This is what is happening with all the people participating in the codechef programming site.

• It's not that people don't try to go to the codeforces website from codechef. It's just that they find it difficult to start switching from a 10-day contest to 3-hour contests.

In general, it takes patience and practice to switch to the codeforces website from codechef, which people cannot give and therefore only stick to codechef.

Those who can participate regularly and practise 3 hour programming contests with seriousness start doing well on codeforces and with this they also start to like the codeforces website and it’s environment.
