### Từng ngôn ngữ riêng biệt
**Bạn phải chọn một ngôn ngữ cho cuộc phỏng vấn (xem ở trên).** Đây là các khuyến nghị của tôi. Tôi không có tài liệu cho tất cả các ngôn ngữ lập trình, vậy nên, đóng góp từ bạn luôn được chào đón.
Nếu bạn muốn đọc xuyên suốt một trong những quyển sách này, bạn nên có kiến thức về cấu trúc dữ liệu và giải thuật. Bạn cũng nên luyện tập giải toán lập trình.
**Bạn có thể bỏ qua bài giảng video trong project này**, trừ khi bạn muốn tự đánh giá lại kiến thức của mình.
