Method 1:
Everyone can think of it. Calculate the value of a * B and then calculate the value of a * B mod C. This is the simplest, but there is a drawback: the value of a * B cannot be too large and may overflow.
Method 2:
Review the knowledge of hexadecimal conversion. Binary C
the MoD installation tutorial
Step one: Click on the game settings to find MoD admin and click
Step Two: Find the Add Word and click, Pop Select MoD window
Step three: Find where your mod is and click on MoD to add it at the end of the click and open
Fourth
After the previous configuration, the MoD has been shown in the list, but there are two lines below, indicating that no mod information, hit your mod the author of a meal let him fill the mcmod.info.So come and fill in the MoD information.Src/main/resources folder in the configuration of the time should have been autom
Just learned not long, online also did not have many MoD development tutorial, can only own an interface to look at the past.So called development research.The focus is on research.It means that if I write half of it and I can't write it down, I'll ditch it.Compared to the people of my spectrum:http://www.hakugyokurou.net/wordpress/?page_id=126http://www.261day.com/minecraft-forge%E6%95%99%E7%A8%8B/http://www.orangetutorial.com/tutorial-list/#sthash.
To be honest, I've forgotten how this mod was written.So the following code can not be run is very normal.On the last book, we dealt with the event that triggered when the player was right-clicking the backpack, sent a command to open the Backpack window, but the Backpack window has not yet been written to solve the problem.This time because there are too many nested relationships, I'm in the reverse order of execution.So, regardless of the last GUI t
The most appealing thing about Android phones is its open source and the pleasure of other third-party apps. Experimenting with windows on Android phones is an exploration project for some mobile enthusiasts, whether remotely controlled or virtual, and there is a new way to do it.

not the same, they create conflicts.
For example, 7/(-3) =-2.3,
Generated two quotient-2 and-3 7 = (-3) * (-2) +1 or 7 = (-3) * (-3) + (-2).
Therefore, 7rem ( -3) =1,7mod (-3) = (-2)
Usually, the modulo operation is called the remainder operation,
They return the result as a remainder. The only difference between REM (take-up) and mod (modulo) is:
When x and Y are the same sign, two function results are equivalent;

Modulo p operation
Given a positive integer p, any integer n must have an equation
n = kp + r
Where K and R are integers and 0 ≤ r
For positive integers p and integers A and B, the following operations are defined:
Modulo operation: A mod p indicates the remainder of a divided by P.
Mod P addition :( a + B) mod P, the result is the remainder of A + B arithmet

A ^ B mod C
Assume 0
1. The original method is to first obtain a ^ B and finally mod C.
However, this method is inefficient, and the time complexity is O (B), and a ^ B must be less than N to avoid overflow. It has great limitations.
2. Improvement Method 1:
Assume a> C, there is a ^ B mod c = (a mod c) ^ (B

The beauty of the original root G of the modulo prime p is reflected in the presence of a non-zero number G power of each modulo p. Therefore, for any number 1

Exactly the same as model a P. The corresponding index is called G-based a model P. Assume that P and G have been given, the index is I ().

Long time no write, in fact, has been doing, but not the mood to write a summary of the article, so or later to do a little bit to write it.Recently the state is very poor very bad, the water problem all can not pass, I am also drunk.Redo last year's two Noip questions, d1t2 and D2T3, which included the MoD operation.The MoD operation basically satisfies the arithmetic, so many expressions are equivalent in
1. Residual: The remainder after the division is divided, for example:
MOD 4 = 2; -17 MOD 4 =-1; -3 MOD 4 =-3; 4 MOD (-3) = 1; -4 MOD 3 =-1;
If a mod B is an XOR, then the resulting symbol is the same as a; Of course, a
The remainder functions of PHP are described in MOD (x, y) and x % y. The remainder function PHP is used to obtain the remainder MOD (x, y) x % yMOD of the remainder function PHP. for example, 93,9 is the divisor, and 3 is the divisor. the mod function is a remainder function in the format of mod (nExp1, nExp2), that i
