, with the application of a new generation of blade servers, the maximum heat load of the rack can be as high as 15 kW to 25 kW. The acceleration of Small-space and high-density computing systems puts forward higher requirements on network performance. Countermeasure: through centralized products and smart wiring, power consumption is reduced while wiring density is increased. Ampu wiring has developed a centralized product series for these environments, which can achieve the design goal of ens

The main meaning of the topic is: There are n ropes, their lengths are Li, if they are cut out of the same length of K-bar rope, the length of each bar of the K-string what can be the longest?This problem can be solved well by binary search.The lengths are 0 to INF (INF is the largest possible number). Then the two-point search, the continuous narrowing of the range, cycle a certain number of times, can be a good answer to find out.G++double to use%LF input, with%f output, C + + is the window, w

The main topic: to a N-point, M-edge of the graph, the minimum point cut set of the cardinality.Problem Analysis: The base of the minimum point cut set of the graph can be changed to the minimum cut. Considering the graph of single source s single-sink T, if a minimum point set is required, so that the graph is no longer connected after the point set is removed (the number of connected components is increased), simply split each point into two (in and out points), and with a capacity of 1 arc, t

The data cable is indeed brokenSolutionIf it is the problem above, we can change the original line. If it is just a charge, we can remove it and then directly connect it.If the above method has been tried and still does not work, the temporary solution is to first shut down and charge the iPhone.Then we charge the iPhone again, bec
