For illustration. Calculates the shortest random sub-ans1. and delete edges. Free to be able to get maximum and short-circuiting between the maximum points ans2 if these two do not communicate. As the shortest distance between two points L.The first idea is to enumerate each edge and then run n the shortest time. However, this complexity is 1000*1000*100*log (100), too large: In fact, at a fixed starting point, the shortest time to find the unit. At the same time can find the shortest single sou

Online shopping has become a mainstream trend, convenient and fast, and basically can guarantee the quality. And the future of online shopping will certainly be more developed, not only the quality has been improved, in the shopping experience will not be as now too flat, so the physical store to a certain extent by the threat. In the future, the physical mall may be more of a pastime than a necessity. In the future there may be more entertainment in the mall, after all, the entertainment experi

 Test instructions: Given an n-node M-edge of the graph, the definition of C for each vertex of the shortest sum, requires the deletion of an edge to re-find a C-value C ', to find the C ' maximum value.Idea: If you use the Floyd algorithm to calculate C, every attempt to delete an edge to be recalculated, the time complexity of O (n*n*n*m), difficult to bear. If Use n times Dijkstra calculates single source shortest circuit, time complexity taste O (N*M*M*LOGN). It looks better than before, b

Now, the logistics company places the goods in the distributed area, such as at the school gate. The pick-up personnel (students, etc.) will collect the parcels that are messy and placed on the ground, in the event of inefficient and time-consuming searching for your own packages, queuing payment, and so on, I would like to express my views on this issue, hoping to give you some tips. The basic idea is to develop mobile phone applications, use mobile

This kind of thinking often makes my life very painful. When you want to finish something quickly, your mind is no longer in this matter. This problem has plagued me for a long time in college. I don't realize that this is actuall
