Informatics Olympic competition

I am the first in the Informatics Union. I've been doing it for three years. I didn't do it well in the first two years, and I started to work hard in the last year.

There are many courses in data structure and algorithm that you have taken. Judging from Olympiad in Informatics, I personally don't recommend this book as the main reference book. But after you read this book, I think NOIP 1= is very close to you now.

I suggest: 1. Buy "Introduction to Algorithms" and "Olympic Competition of Algorithm Art and Informatics" and read according to the guide of the second book.

2. Seize the summer vacation time, do exercises seriously and systematically, insist on combining problem solving with reading and learning new knowledge, and do various problems. I will recommend some online judges to you later. If it is a strong province, if it is 1=, it is almost impossible without 200+.

3. Set up a summary book, write down the brief description, analysis and practice of the topics you have done, and write down the experience you occasionally get. At the same time, get a small "algorithm book", write down the codes of various algorithms and review them frequently.

4. Do the questions of previous years before the initial test, and pay special attention to some required questions-stack and queue forms, binary tree traversal and so on. It takes about 1 week to review the preliminary round.

5. If you don't pass the preliminaries ... see if you can find someone first, or you will prepare for the college entrance examination.

6. After the preliminaries, we will use the remaining 20 days to conduct at least 65,438+00 mock competitions besides the same study as in the summer vacation, and treat them like real exams.

7. The semi-final of165438+will be held in the middle of 10, so we should adjust our mentality.

According to my experience and observation of the students around me, if you can do the above, plus the foundation you mentioned, you are probably at least 70% sure to get into 1=.

The "black book" refers to the "Olympic Competition of Algorithm Art and Informatics", and we sometimes refer to "Introduction to Algorithms" as the "black book" here. Algorithm Art and Olympic Games in Informatics has no definite language, including C, C++ codes and Pascal codes, many of which are pseudocodes. Don't worry, anyone who has studied this language can understand it.

That's all. I hope you come on. Of course, it is best to consult parents and schools first. Even if you agree to participate in the competition, you should take the culture class seriously and be "foolproof". Wish you success!

I think usaco is classic, Vijos is most suitable for middle school students, and POJ has a lot of problems, most of which are English problems, which are very powerful.
