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

phone-So Power Blast at turning on computer or connecting interface into computer. dz1 and dz2 diodes cuts-down this voltage to 2.7 V-it is enough to log. 1 and it is hardly under maximal voltage value. in all, it is standard wiring of max232. pins No. 8 (r2in) and No. 9 (t2in) You needn't to connect to ground. If you use a maxcompute is necesary use a 1 K ressistor to reduce voltage at pin 10 from I. c. so we guaratee a correct voltage at Tx for the phone and it's not necesary 4007 diodes beca

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

Cause analysisI. Check whether the data line of iOS7 and later versions is original2. The data line interface is dirty.3. 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

Network cable is not enough, the computer can connect the router set up the Internet? OK. The router can emit a default wireless signal tp-link_xxxx in the factory state, and this signal has no password. You can use a mobile phone, notebook or pad to connect this wireless signal, open a Web browser, enter the router's management address (tplogin.cn or 192.168.1.1), you can log into the router management interface. After you log on, you can follow th

After connecting the monitor and the host with the HDMI cable, the monitor does not have any images when you start the computer. LCD technology can make computer monitors and televisions connected together, with this function of the TV is also known as LCD TV, on the one hand can watch TV through the TV interface, on the other hand, through the VGA, HDMI interface with the computer, acting as a computer monitor. You can also connect to the DVD

What if the Mac suddenly connects to the cable network and can't get online?
