A question that sets out all the more important theorems of number theoryIf you have not learned the fast power, Fermat theorem, Lucas theorem, the Chinese remainder theorem , please turn off the computer science and culture class, Oi is not suitable for you , please go out to the left of Baidu/googleThis is the big stupid question.In addition to pay attention to the special n=p-1, Fermat theorem is not established, direct output 0#include 　　bzoj1951: [Sdoi2010] Ancient

DP[I][J][K]: Walk I step respectively (can also be understood as radius i), A to J line, B to the number of palindrome K line. The radius of the walk is gradually reduced.It can be known that the X1 line can only be transferred by the previous X1 line or x1+1 line, and the X2 line can only be transferred f

So consider narrowing the size of this long long array. Then think of the sub-block may be 15 for the size of the block, in fact, not a little more than a small, but the memory 15 is similar to it. Then record each block within the and, and then ask when the whole block directly take, not the whole block of violent enumeration, at most 30

The group statement can put data with the same key valueAggregationTogether, there is an essential difference from group operations in SQL, where groups created by a group by sentence must be injected directly into one or more aggregate functions. There is no direct relationship between group and aggregate functions in pig Latin.

This question is the question of the combination of various number theory... The answer is ans = (G ^ sigma (C (n, d) % Mod. Then, by the ferma's theorem, ANS = (G ^ (SIGMA (C (n, d) % (mod-1) % mod Then, mod-1 is decomposed into 2*3*4679*35617, and Sigma (C (n, d) % m (m = 2, 3, 4679,356 17 Finally, we can combine the Chinese Remainder Theorem to quickly power the power! 1 /************************************************************** 2 Problem: 1951 3 User: rausen 4 Language: C+

Pig New System Test 3: iOS8.0.2 Originally, this cat had to wait for version 8.1 to come out and then perform the test again. Wait until the result is reached, that is, it was too late to push updates! What about iOS October 20 in 8.1? In an effort to write it up, I will not wait. Let's test the iOS 8.0.2 system! The 8. x System and the 7.1 system are still quite similar, only in some places are different. First, the screen display function is added t

Pig New System Test 4: Ubuntu 14.04, ubuntu14.04 At present, modemo generally uses the wubantu System in the office. On the one hand, the reason is that the old nature cannot run Windows. More importantly, the cat thinks that the Linux system is more open. besides, I am familiar with it now, and can be completely isolated from Windows! In this series of four new system testing articles, besides what iOS8 wrote on mac (it seems a bit too much to write
