In the Problem description young singer Grand Prix, the jury scored the contestants. The contestant scoring rule is to remove one highest score and one lowest score, and then calculate the average score. program the score of a contestant. There are multiple groups of input data. Each group occupies one row. The first number of each row is N (2 # Include Int main (){Int N, I, j;Double A [100];While (scanf ("% d", N )! = EOF){Double S = 0, M1, M2;For (

PPMM can only execute six simple commands a, B, c, d, e, f; only two memory M1, M2; three registers R1, R2, R3. The meaning of the six commands is as follows:

is an integer that satisfies (a, m) = 1, and B is an arbitrary integer, if X traverses a completely residual system of M, then, ax + B Also traverses a completely residual system of M.
Proof: because (a, m) = 1, we know that a * m is required to return to the origin. That is to say, ax can traverse a completely residual system of M, then + B can traverse the entire residual system, but the position is not correct.
Theorem 4: Let M1 and M2 be the Posi

Title DescriptionDescriptionDr. Hanks is a leading expert in the field of BT (Bio-tech, Biotechnology). Now he is preparing for a cell experiment: culturing cell samples.Dr. Hanks now has N species of cells, numbered from 1~n, and an I cell can be split into Si cells after 1 seconds (SI is a positive integer). Now he needs to pick one of the cells and put it in a petri dish and let it split up and grow. After a period of time, all the cells in the petri dish are evenly divided into m-Test tubes

Before touching the soft worker this semester, there is only one understanding of software engineering: writing code. Through this semester two team development stage, gradually to the software engineering has a more in-depth understanding, self-thought already has the most basic team development accomplishment and ability. I am a member of the Love Code room team, in the M1 stage due to the lack of experience, we can only follow the teacher's suggested development mode

The radius of the photon is the distance r of the positive and negative electrons, and also their sma
Fever fish:Recently, some netizens often asked me how to renew my earphones. In fact, I have never been reluctant to deliberately hide a pair of headphones, because if it is done well, it is just a little faster to enter the status, such as hd600, it would have taken about two hours to get into the status every day. However, if you do not have a hard time, it may shorten the service life of your earphones and even cause permanent physical damage to your earphones, for example, when I found someo

Well, personal advice to wear these two different headphones do not stand together.In case, I mean in case,

If a user deletes a file in a directory that is open by a running app, the value returned by the du command displays the size of the directory after the file has been subtracted. However, the DF command does not show the size after subtracting the file until the running application closes the open file, and the value returned by DF shows the file system usage after subtracting the file.Use DF command to show the fr
I personally think the convolver in foobar2000 is quite powerful. I used dfft to simulate the tone of vacuum tube and classic headphones. I still wanted to create a machine, but I couldn't buy any materials. You can go to foobar2000's old nest to see how to download the impulse file package dedicated to convolver. Recently, I want to carefully study which impulse is the best. First expose my audio device, old sblive 5.1 and Cambridge bookshelf audio, kx 3538 driver, Windows XP. The self-built AS
