This is a code big problem. First read the wrong test instructions, and then understand the direct look of the kind of adjacent, and then do not want to pass a long time!!!Separate the diagram of the different unicom, and then pre-preprocess the formation of the adjacent diagram after the state, and then according to 01 to determine which is the need to change the state, and then build a diagram, using the binary diagram km algorithm to match the optimal scheme. Then find each group of replaceme
chips to FPGA by the system clock. Figure 1.3 FPGA data input model The input delay is the delay time from the external device to the FPGA input port. This includes the latency from the clock source to the FPGA, the latency from the external device, the TCO of data transmission from the external device, and the cabling latency on the PCB. As shown in Figure 1.4, It is the timing of the external device and FPGA interface. Figure 1.4 timing of external devices and FPGA Interfaces1. maximum inp

GCC is the GNU exclusive C/C ++ compiler. Because GCC has compatibility issues, you must use the specified version of GCC to compile and pass the code, therefore, we should switch to the appropriate GCC compiler in a timely manner. 1.

reduced to AD and BC, must be intersect?It turns out that this proposition is not necessarily, but it can be found that when it can be reduced to AD and BC, AD and BC must be disjoint. Doing so will result in AD+BC > AC+BD.So as long as can reduce the side of the right and, must be able to ensure that disjoint. Then the final state becomes the edge right and the smallest state, which is the minimum match. Can be done using the KM algorithm.Appears to be a data problem and cannot be processed us
HDU_2426 This topic is a perfect match for the maximum right. we need to pay attention to two points: 1. Deal with the negative edge. 2. Note that N and M are not necessarily equal. For the processing of the first point, I have seen two ways to deal with: ① all the sides are initialized to the negative side, so that as the N-M between all the edge is to exist to match, if the number of matches with the positive edge weight is N, there is a solution. Otherwise, no solution is available. ② The e

As mentioned above, high-precision timer is implemented through hrtimer. hrtimer uses a programmable timer to present it. It does not occupy CPU while waiting. In the user State, when we call usleep, the thread will use hrtimer to wait for CPU usage during kernel state execution. How to use it in kernel? Let's take a look at the ep_poll function in eventpoll. C: static int ep_poll(struct eventpoll *ep, struct epoll_event __user *events, int maxevents, long timeout){int res = 0, eavail, timed_
