Title Address: HDU 4389The first time you encounter a need to enumerate and then the digits DP.The sum of the numbers is enumerated first, that is, 1~81, then the sum of the enumerated members in the digital DP process is the same as the number of enumerations, only the same counts.DP[I][J][K][H] denotes the number of digits of the current number of members, and for J, the number of members enumerated, and K, the current numbers of K modulo H.The code is as follows:#include #include #include #in

Link to the question: Ultraviolet A 10692-Huge mod
Give the power of a number, and then it modulo the M value.
Solution: based on the nature of the residual series, the last line must be cyclical, so there will be AB = abmod (phi [M]) + phi [M] (phi [M] is an Euler's function of M), which can be solved based on recursion.

Question: PleaseA0A1A2...MODM
Idea: it is certainly not possible to calculate it directly. Use the Euler's theorem.AB=A(BMODPHI(M) +PHI(M))(B> =PHI(M). Then, we can use the fast power to calculate the exponential value, and the calculation process is recursive.
Code:

In this question, 2 ^ X is obtained cyclically and then mod n = 1, and the time exceeds.
Use mathematical formula (M * n) % d = (M % d * n % d) % d to simplify the scenario.
The Code is as follows:

Http://acm.hdu.edu.cn/showproblem.php? PID = 1, 1005A number sequence is defined as follows:F (1) = 1, F (2) = 1, F (n) = (A * F (n-1) + B * F (n-2 )) moD 7.Given a, B, and N, you are to calculate the value of F (n ).1
Solution:F (n) = (A * F (n-1) + B * F (n-2) % 7= (A * F (n-1) % 7 + B * F (n-2) % 7) % 7Therefore, for a given a and B, You can first create a table to find out the cyclic part of the series. The Pigeon nest principle knows that the to

Some of the modules installed here are not commonly used but very good, including mod_evasive, which prevents server attacks, mod_security for security protection such as injection prevention, and mod_deflate for web page compression.

Typically, modulo operations (MoD) and remainder (REM) operations are confused, because in most programming languages, the '% ' notation is used to represent modulo or remainder operations. Here we want to remind you to pay attention to the specific meaning of the '% ' operator in the current environment, because in the case of negative numbers, the results are different.
For integer number A,b, the method of modulo operation or remainder operation i
Research on Web worker multi-thread API in JavaScript, workerapi
HTML5 supports APIs such as Web Worker, allowing Web pages to execute multi-threaded code securely. However, Web Worker is actually subject to many restrictions because it cannot truly share memory data and can only use messages for status notifications. Therefore, it cannot even be called a real "m
", a new solution is also proposed in HTML5, which is Web Worker. Web Worker is to use the Worker class to open up an additional thread in the current main JavaScript execution thread to load and run specific JavaScript files, the new thread and the JavaScript main thread do not affect each other and block execution. In addition, the Web
