Why is CodeChef so difficult?

@emely CodeChef is a platform to help programmers succeed in programming contests, algorithms, and computer programming. It provides a space for programmers to practice programming without any restrictions.

People who have participated in contests with CodeChef might be puzzled why it is so difficult. One reason is that the problems are diverse, including problems related to data structures, algorithms and complexity analysis, combinatorics and graph theory, deep learning, etc. Another reason is that the contests are difficult. They rank you based on whether you answer the problems correctly or how fast your answers are. Even then, CodeChef is also one of the best platforms for practice because it constantly challenges you with many problems that need to be solved creatively.

Also, every contest has a time limit for each question. This makes the contests difficult because you have to decide whether to leave some problems unsolved or answer them before time runs out. It would be best if you also dealt with questions that are hard to solve, and you might encounter problems whose solutions are not found easily on the Internet. The contests also test your endurance, so keeping calm and focusing on the problem is important.

Finally, CodeChef contests are difficult because you can't access the source code of the problems. You have to figure out the source code by looking at the input and output data. This becomes almost impossible if the problem is about innovative machine learning algorithms or advanced mathematics or involves some tricks or logic that are difficult to process mentally. In such cases, you have first to decode what is happening and then think of a way to solve the problem.

Overall, CodeChef is difficult because it offers a wide range of challenging problems, competitive contests, limited time constraints, and a lack of access to the source code. However, these difficulties make it a valuable platform for improving programming skills and problem-solving abilities.
