HDU 4411 Arrest fee stream Question link: Click the open link Question: Given n + 1 vertex ([0, n]) an undirected graph of m edge. The starting point is 0, and k people are initially at the starting point, Traversing the graph enables at least one person to walk each vertex and the I-1 must have been traversed when traversing the I point. To minimize the path and number of k people, k people should return to the starting point. Ideas: Cost flow, because for a person, the sequence of the person's

Ubuntu introduction ----- animation! Almost all members of the design team attended the UDS conference in Orlando this week, just as we were working together for exciting things in the past few weeks. You may have seen our authorized video recordings indicating what Ubuntu is. This is an organization used by our partners to promote open-source and specialized branch versions, not just video playback, it can play whatever you want to display. Create im

cool. 14) C # was first talked about widely at a PDC. What year was it? Where was it held, and How hot was it?A) 98 DegreesB) hotter than a jalapeno in a heat waveC) hot enough to make your palms sweat at AMD) hot enough to lose 20 pounds in 20 days, ask me how! Reliable sources suggest that the year was 2000, and that it was held in a hotel steam bath. others suggest that it was held in Orlando, and further others maintain that there is no practical

In 2014, the Gartner seminar was held in Orlando. Experts successively published various topics. At the end of the seminar, the ten strategic technology trends of information technology in 2015 were also proposed. Including IOT, 3D printing, analysis technology, intelligent machines, cloud/client architecture, and network scale it. Gartner symposium/itxpo Technology Summit is being held in Orlando. As usual

Calvino's mind is always full of fancy ideas. It is said that someone has found the structure of other people from his head after his death, and I would rather just believe that it was just a compliment to a great writer who died. But there is no denying that such a yarn is not unfounded, if you have read any of Calvino's novels, I believe you must be in his book The Empty imagination simply astounding.In the series of our ancestors, the strange-character man walked on every page of the book pap

the point is a unicom block.This way we are going to enumerate the root nodes and merge only the parent-child-grandchild.Then the complexity is O (n^2). We can optimize the change root, do not have to change root every time to enumerate, if each time only the current root node is not the root of the son, will be re-DP of only two points, the root of the complexity O (1) So the total complexity O (n) and then started with the vector what, Bzoj, Cena on a cool cold to the STL, forced to see someo
