Hi everyone,\n\nSpringer publishing has made a very nice selection of (under)graduate books in Computer Science freely available due to the Covid-19 crisis. You can find them all [here](https://link.springer.com/search/page/3?facet-content-type=%22Book%22&package=mat-covid19_textbooks&facet-language=%22En%22&sortOrder=newestFirst&showAll=true&facet-discipline=%22Computer+Science%22). The topics range from Python basics to advanced Data Science and Neural Networks. Especially [this book, the Guide to Competitive Programming](https://link.springer.com/book/10.1007/978-3-319-72547-5), seems like it can be useful to people who are practicing and improving their skills on LeetCode.\n\nEnjoy!
