Can I directly output the answer of the sample data in the NOIP information semi final to score poin

Answers that directly output sample data may work, but samples are not necessarily included in the test data.

An easier way to cheat points can be to hit a table (in the data range hours) and as for the flash search, for example: finding prime numbers.

Normal version. var i,j:longint;

a:array[1..101]of boolean;

beginfillchar(a,sizeof(a),true);

for i:=2 to 100 do beginif(a[i])then begin

j:=2*i;

while j<=100 do begina[j]:=false;

inc(j,i);

end;end;

end;for i:=1 to 100 doif(a[i])then write(i,' ');

end.Raid version.

var a:array[1..1001]of boolean;

i,j,k,t,n:longint;

beginreadln(n);

for i:=2 to n do a[i]:=true;

for i:=2 to 1000 do

for j:=i to sqrt(j) doif i mod j=0 then

begina[i]:=false;

break;

end;for i:=1 to 1000 do if a[i] then write(a[i],' ');

end.The main reason is the difference in data, because I don't know how to optimize it, I search wildly.

Make the most of scratch paper and don't be too confident in your "mental arithmetic abilities"! Students who are proficient in programming like to "do it in one go" and start coding when they get the questions. I don't think that's good, the thought process of doing informatics competition questions is rich and tortuous, and the consideration of the problem must be comprehensive, and programming based on a momentary "feeling" is often full of loopholes.

For example, beginners often forget to do some initialization work (far more than the simplest thing like assigning initial values to variables), and even experienced students will inevitably write a few wrong sentences due to a moment of negligence. The worst thing is that the algorithm of the "first feeling" is wrong or too inefficient (the trap of the proposer), and the program is mostly programmed only to find that the time is wasted, not to mention, but also affects confidence and performance.

When the time comes, you'll be given a test paper that says it clearly.

Folder names are generally uppercase.

Only sample test data.

devc++ vc

There are restrictions, no, you will know why when you see the submission form.

I don't know, I've used it, but I don't know how to do that question to cheat points.

DevC++ is used

There are restrictions on header files.

I haven't heard of either of them, but I don't think it works.

NOIP is divided into preliminary round and semi-final.

The preliminary round is a written test, and the multiple-choice questions rely on the basic knowledge of computers, such as the history of computer development, the data structure of computers, and the methods of operation (binary, octal, etc.). Wait.

There are also 2 fill-in-the-blank questions, which are generally tests mathematical ability.

There are also 4 questions of program reading (the most important scoring question), which requires you to write the results of the program run, and the first question is definitely to give points.

Finally, it is necessary to improve the program, give a program, and dig out a few blanks for you to fill.

The semi-final is computer programming, 4 questions, and 3 hours of testing.

It takes a long time to learn this, but if you're willing to work really hard (or you're smart) in September, you should be fine in the semi-finals. It might be a little difficult to get to the rematch.

I also studied in junior high school, but at that time I didn't work hard enough, and I didn't have anything to be proud of, but I hope you can stick to it, because learning those programming requires not only good thinking skills, but also a lot of patience and perseverance to really learn well. Don't learn from me before.

If you can win the first prize in high school, you can get a good university!

The National Informatics League (NOIP) is divided into preliminary and semi-final. Of course, you are in the popularization group.

The preliminary round is a written test.

After reaching a certain score line, you will enter the semi-finals.

The semi-final is a computer-based test. There are 4 questions, generally one question is 100 points, and there are 10 test points.

When you test it yourself, write one yourself, use notepad, and change the file name to the corresponding one.

The output file should be automatically generated.

Please refer to the following for how to use it

You don't have to just hand over the source**, and individual provinces require it. exe file.

The input and output files are the ones he uses to evaluate your program.

No, just one. source program file for PAS.

You don't need to use in and out files, just put the source program in the specified folder.

The input file is provided by the contest to test the correctness of your program.

All you need to do is submit a program that can read the input file and produce the output file and its source.

When the contestant evaluates, it is by providing input files to your program, but running your program, and getting the output file generated by your program, you can know whether your answer is correct or not by comparing the output file, and when running your program, it will calculate the time for your program to run as a judge of time complexity, as well as the detection of memory usage.

This can be referred to, there are some past test questions and practice questions above, which can be used for reference, as for the content of the exam, it can be involved, there are about one or two test program design, most of the others are algorithms and the like, mainly to look at the problem of the algorithm, about this aspect lz can take a look at the reference reference of the past test questions on the **.

Every year, probably in November.

Please refer to the official website for details of the registration time (the registration seems to be a unified report for each junior high school, and there is no outline.)

You can choose the C C++ Pascal language.

Compiler: c:gcc

c++:g++

pascal:fpc

If you win the award, there is a specific score, depending on the situation every year, generally more than 200 points to win the first prize book "black book" should be enough.

The content focuses on algorithms, and generally speaking, the first question is to send points.

The preliminary examination is a written test, which focuses on the basic computer knowledge and programming ability of students, and tests the breadth of knowledge. The programming descriptor language is Basic (abolished in 2005), C (partially abolished in 2022), C++ or Pascal (abolished in 2022).

The top 15% of students in the preliminary examination of each province and city will enter the semi-finals, and their scores will not be included in the semi-finals. The preliminary round will be held on the second or third Saturday or Sunday in October from 2:30 pm to 4 pm

30 or 1:30-3:30.

The re-examination is in the form of computer-based, focusing on students' ability to analyze and understand problems, mathematical abstraction ability, ability to control programming language, programming skills, imagination and creativity, etc. Programming languages can be Basic (abolished after 2005), Pascal (phased out in 2022), C (partially phased out in 2022), or C++. The ranking prizes of the provincial and municipal competitions are selected from the winners of the re-examination.

The duration of the semi-final popularization group is hour. It is only tried once, and it is held on the third Saturday of November of that year.

In order to strengthen the credibility of the competition results, since 2011, the semi-final improvement group has been changed from one test to two tests, which will be held over two days. The number of questions in the daily competition has been changed from 4 to 3.

NOIP stands for National Olympiad in Informatics in Provinces.

The preliminary round is only a written test in your own city, and the test is mainly based on the basics.

The semi-final is held in the province There are four questions with a full score of 400 points The first prize score line in most provinces is generally a little more than 100 points The difficulty is much greater than that of the preliminary round The main test algorithm. C, C++, and Pascal can be used in the semi-finals, and after 2022, Pascal and C will not be available, and only C++ will be used.

Past preliminary and semi-final questions can be found at or .

NOIP is organized by the commissioner at the same time and in different places in each province and city. Unified national syllabus and unified test papers. Students from middle, high school or other secondary specialized schools can sign up for the league.

The league is divided into two stages: preliminary round and semi-final. The preliminary round examines general and practical computer science knowledge and is conducted in the form of a written test. The semi-final is a program design that must be debugged on a computer.

Participants in the preliminary round must reach a certain score before they are eligible to participate in the semi-finals. The league is divided into two groups, the general group and the advanced group, with different levels of difficulty, and is aimed at students at the junior high school and high school levels.

The junior high school group and the high school group are also divided into preliminary and semi-finals, and if you want to know more about it, you can go to the Code Fun College for consultation, because many things in the course still need professional answers.
