It is not difficult to solve this problem, open two-layer loop to traverse can be achieved, but will time outIf I wanted the time complexity of O (n), I would consider using a hash table to store the traversed element, and if I found the currently traversed element in the hash table, that means the intersection is here.This takes advantage of the hash table lookup time is O (1)However, this algorithm does not meet the requirement of O (1) for space complexity.The code looks like this:1 classsolu

diagonal crossover pattern, but this time we're going to use 8 pixels multiplied by 8 pixel documents, why not the previous 7 pixels? Just think about it. A pattern with an even pixel size can make the intersection of two diagonal points at the center of the document. So this time we're going to use an even pixel size document.
1, create a new document (CTRL + N), 8 pixels multiplied by 8 pixel size, using the magnifying glass tool to enlarge it to

These two days want to try the TFTP download function under the Uboot, so to establish the Development Board and Ubuntu Network connection, encountered some problems in the middle, is recorded, lest forget.

As shown in the figure, PC0 is connected to the F0/1 interface of Switch0, PC1 ——-SWITCH0/2,PC2--SWITCH1/1PC3--SWITCH1/2, and then the switch uses a crossover line to connect their third interface
Note: Direct connection is required between the host and the switch, and the host IP address needs to be configured with a crossover line between the switches

In recent years, with the "network economy" bubble burst, the optical communications industry's capital expenditure greatly reduced, as the optical communications industry chain at the bottom of the optical electronic devices industry is facing a very big challenge. It is estima

As a result, mapping from phenotype to genotype is required at the outset to encode work. Since the work of the gene coding is very complex, we tend to simplify, such as binary coding, after the first generation of the population, according to the principle of survival of the fittest and the fittest, generational (generation) evolution produces a better approximate solu

Of course, if the local area network in which we are located is not very large and only contains the number of workstations, you can also directly use a non-

You can use GMPLS to dynamically provide resources and provide

But later on the internet to see, in fact, TFTP is also available, and the efficiency may be higher. The following

This article describes how to use a wireless router in detail, and provides detailed instructions and configuration steps. I believe that after reading this article, you will have a clear understanding of using a wireless router.
A wireless router has a network cable that can be connected to its parent device (such as a vswitch or vro, or an Internet connection point such as adsl cat ), connect the covered wireless network with other networks (wired or wireless. If the access point is an ADSL ca
