Hello I am a student studying AI. I need a dataset to learn the AI model and I want to get a large dataset from Codeforces. This dataset must consist of the problem number and its topics, many of AC source code, and each of programming language. I tried to crawl to get these datasets, but I have a question before that. Is it illegal to crawl other people's source code in Codeforces?

Found several blogs that have already been crawled. https://codeforces.com/blog/entry/54384 https://codeforces.com/blog/entry/43943 https://www.kaggle.com/agrigorev/codeforces-code Thank you for reading it.
