@metin Great find, Metin! I looked through the table of contents and it looks very useful 👍 Gaining knowledge of math and computer science concepts early on is extremely helpful, as these skills are required before the relevant courses begin, which can take months or even years. My university offered special courses in both subjects in the first semester, and I'm extremely glad they introduced them shortly before I started. It's good to have a well-designed book that everyone can use!
