The input stream, the output stream is exactly how to distinguish, in writing code often encounter problems, or often confusing to find two of the relationship between streams. Through today's study to make a note, but also to provide everyone to learn, at the same time ask me questions. The book saysInput stream: Data can only be read from and cannot be written to.Output stream: Data can only be written to it and cannot be read from. So I have a question, what the hell is this stream? The b

Volley is used to implement waterfall flow, and volley is used to implement waterfall Flow Today, I stopped php and studied the source code of the Volley framework to implement the waterfall flow. To achieve the final waterfall effect, you need to have some knowledge: (1) custom layout. To listen for events that slide to the bottom, we need to implement a custom

A long time ago, I tried to overcome the problem of network streams. I think this part of content seems very advanced, and I think there are still many other algorithms to learn, third, I think it would be better to supplement the relevant algorithms first. However, although this is a relatively advanced graph theory, it is still not difficult to build a foundation, and there are not many related algorithms. You can learn it after you are familiar with graph theory, the algorithm can be learned

This article uses a C program to explain the entire message execution process of the socket in Linux. C program example /*************************************** * **************

In (b), 4 and 6 cannot are powered, since there is no directed path from junction 4 to the negati

Network maximum flow algorithm-EK algorithm, maximum flow ek AlgorithmPreface The EK algorithm is the most basic algorithm for finding the largest stream in the network and a well-understood algorithm. It can be used to solve most of the largest stream problems. However, due to time complexity constraints, such algorithms often have the risk of TLE.Thoughts Do you still remember the solution ideas we mentio

The so-called waterfall flow effect is just like the light bed home effect, a number of similar columns closely arranged, as far as possible to the gap between the smallest (i.e. fluid layout), and as the page scroll down, the new data will be appended to the end of the current page until all data loaded (scrolling triggered Ajax page). Waterfall Streaming triggers paging Here's a thought, though not all of the following examples can be used:1. When
