brute Force enumeration z, check whether z conforms to requirements, obviously when Z is prime number is compliant, by the prime number theorem can get, Z's enumerator at Logn level complexity O (\sqrt[4]{n}log\sqrt[2]{n}?4??√?N???LOg ? 2 ?? √ ? n ? ?? ) just need to enumerate around X, the scope of the enumeration is very small ... Then z to determine whether the condition is satisfied is also very simple. Code
Oilfield problems (L-Brute force solution, DFS)DescriptionThe Geosurvcomp Geologic Survey company are responsible for detecting underground oil deposits. Geosurvcomp works with one large rectangular region of land at a time, and creates a grid that divides the land into Numer OUs square plots. It then analyzes each plot separately, using a sensing equipment to determine whether or not of the plot contains oil. A plot containing oil is called a pocket.

Yesterday, an MD5 brute force cracking tool was installed in Python due to a hand mark.
In the duration, the method for calculating the n times of the string is optimized, and version 0.2 is implemented.
Then I found that the generated sequence had some problems, so I switched back to v0.1 and then improved it. Low efficiency.
The maximum latency of the single-object string on my Intel Core Duo t6670 is 5 W string/sec

With the deepening of the understanding of the assembly code and the improvement of the level, the study of PJ suddenly generated a dream one day, why do we manually analyze the section where the core code is located, why can't I find it? Why can't I use my mind to automate the program and achieve the goal of improving PJ? Why are there password computing tools such as od automatic shelling scripts, WinRAR, and lucky cracking tools on Android? Why don't we try it? The following tools are born.Mo

Calculate the maximum public substring of two strings, which can be easily solved through dynamic planning. However, it is complicated to encounter the largest public substring of N strings. on the Internet, it is said that the suffix array should be used to solve the problem. This method is still being studied. I will use a brute force method to run it, let's see how efficient it is.
The solution here is prone to a wrong solution, that is, some of m

PS: This brute-force password cracking tool is quite powerful and supports online password cracking for almost all protocols. The key to cracking the password is whether the dictionary is powerful enough. Social engineering penetration can sometimes get twice the result with half the effort. This article only explores the test from the security point of view, and uses the content of this article to do the damage, it has nothing to do with me.

The distance between these points is the same.Analysis:The code below is the first great God in our room. It is very concise and I have the same idea as him, but I don't know where the error is.The idea is brute-force enumeration. There can be a maximum of 10 points. Use floyed to calculate the distance between each two points, and then use
