Test instructions: Given two number l,r, this is the nearest and furthest two primes between the two. The data range is the upper bound of integers. R-lAnalysis: The general idea is to find the prime number between L and R, and then iterate over the minimum distance and the maximum distance. It is unrealistic to preprocess all the primes in the data range with a function, where the array cannot be opened so large and then times out. Think of the idea
A few weeks ago, someone found a new zero-time-difference Adobe Acrobat/Reader vulnerability on the Internet and immediately began to exploit it. From a technical point of view, this attack is most striking because it uses the Return-Oriented Exploitation (ROP) vulnerability) tips to avoid Windows Data Execution Prevention (DEP) security mechanism. In addition, it uses two-stage attack program code (shellco

Recently the format used the encode, found that it has a great improvement than CS6 AH.Prerequisite: Encode is a decoding software. I usually convert it to H. mp4 use. Drag the video file into encode and we'll see a new one added to the task list. The default conversion format is exactly what I need.When a picture is placed in the encode as a source, it is considered a 5s video. So if we need to do a long-time static video, we can copy a picture in la
This new technology is a shooting feature called "Monument Mode". When used, your camera/cell phone can automatically remove the visitors and other disturbing images (such as sudden car passing, etc.). When we shoot the scenery, we always hope to get no people's picture, but in fact, especially when traveling, the front is always coming and coming. This is usually the result of direct shooting:
General situation, to have a lot of people in the scenic spots, no one shot out of the picture

I once went to a company interview, encountered such a topic: ask for the number of primes within 1000 how many? Use multithreading to achieve, and give time to consume. I thought for a while and didn't come up with a multi-threaded solution. Today because of the opportunity, I talk about my solution.This problem obviously has to consider two questions:1, multi-threaded issues2, algorithm performance problemsSome people think what algorithm performanc

Recently in reviewing the content of data structure, especially how to calculate the time complexity of an algorithm.
In the course of solving the problem, we find an efficient algorithm of prime number solving, and analyze the time complexity of the algorithm.

Find the maximum K so that m ^ K can be n! Division
M ^ K is to increase the number of each prime factor of m by K times, as long as N is obtained! It is enough to increase m by multiple times. Of course, the least increase factor is required here.
