It's almost three o'clock to have dinner at noon. In the group, it seems that zoj has a game, and it immediately kills the game.

Read itStatisticsDetermine the sequence, and then do C. Sure enough, the water is to check the sequence of the twelve zodiac signs (Ignore Me). After.

J is also very watery (in fact, I had three questions in this game, AH ).

Then, G is more difficult than the first two. The background of the question is Gaussian prime number.References(In fact, I don't need to read it, but I don't understand it ),

Later, I wanted to use symmetry to optimize the speed. I didn't know where I got it wrong. I went through wa, the tragedy, and finally I went through enumeration to judge every coordinate. The result was .... (This tells us to calm down when the data volume of a question is small, so don't bother yourself ).

Then I started to think it was quite simple at the beginning, that is, it was a little annoying to describe the question. So I started to think about it and found that it was even more annoying to think about it. Many things were not taken into account at the beginning. Therefore, I is the kind of abnormal simulation questions (I found many simulation questions in this competition ). The time is not long, And I is still not finished. Finally, I scanned another question, over.

 

Summary:

There are many simulated questions in this competition, as if they were focused onAlgorithmThe number of questions is relatively small. Moderate amount of questions.
