Empty talk wa, practice AC.

Therefore, as an oier that is about to go to the battlefield, practice is of course the most important thing, but there are not many questions to be asked. The key points should be kept in mind. Although this scum is not remembered much, but there are several points worth noting.

1. Make no mistakes on the battlefield.

For the oier who needs to knock on the keyboard every day, the mistaken program is of course a common issue. However, if the mind is exhausted during the competition, the future may be interrupted, therefore, the investment in the competition should be no less than the soldiers on the battlefield. They will focus on every question, the full score of the water question, the difficulty to score, and the question to score.

2. File pitfalls.

Every program has a name, and when we successfully make this question, it is easy to connect to end immediately after writeln. always forget to close. This is also fatal. Of course, there are still file names. Please never forget to make a mistake.

3. Various sorts are sent to torture you.

Sorting: The knowledge that must be used in each competition. Although it is common, there are always people falling behind (@ miaoyi). It is either a fast sorting error variable or a randomization error (@ fly ride ). Therefore, it is best to verify the correctness after each sorting.

4. Check the art.

When you suspect your program, check is essential. you can insert some output in the original program to check, but at the end of the check, do not forget to delete the added check or //. We recommend that you use watches.

5. If you do not want to press it, click it.

In fact, the memory is no less important than time for the program. Do not blindly pursue S and decisively add a few zeros, or open for a Large Point, it is very important to calculate the memory because the memory limit is exceeded.

6. algorithm review.

There is nothing to say about this. It is to practice all the familiar and unfamiliar algorithms. Write one.

7. How convenient type is.

I have to say that the record type is much better than avoiding arrays. Therefore, skillful use can improve efficiency. Don't make a mistake...

8. variable name.

The game is not a normal code, and you cannot play the game. So the variable name should be well typed. Don't mess up p, q, XX, XXX, or something. If it is wrong, it will be finished.

9. 10. Believe in yourself.

Even if it is violent (@ Zhengyu Niang), you must finish it with confidence. Even if you cannot get the full score, you must finish it with confidence. Even if it is difficult to score points, you must also be confident. Because we are oier. Because this is our war.
