hdu5215 thought first can find the odd ring and some even ring by the two-part graph dyeing. This is relatively simple, but there is a kind of even ring easy to ignore. (Don't ask me why no node 4) This singular ring can be found for the first time, and the second time can be found (3-5-6-3) this odd ring. But (1-2-3-5-6-3-1) This even ring is ignored. One more situation, we can find (1-2-3-4-5-1) This singular ring, also can find (3-4-5-6-7-3 this odd ring), but ignored (1-2-3-7-6-5-1) this eve

, PF_RING is a more efficient solution, which is not only efficient but also flexible. If you have a multi-core processor, you can even process data packets at various layers in the user State in parallel, as shown in: PF_RING caters to the multi-queue feature of modern high-end NICs. This is the truth, but even if it does not support multi-queue NICs, if it is processed according to the current Linux kernel protocol stack, assuming that a specific CPU is interrupted (in fact, Linux's balance

each passenger is assigned travel items. At the beginning, a gave 6 copies to the passengers on the right. At this time, B came to her and said that a should be responsible for the passengers on the left. So a began to issue the goods again on the left, B went on to issue the items to the remaining passengers on the right, and then sent 15 copies to A, and the last two ended their work at the same time. Q: Who sent more messages from a and B? How many copies are sent? A chain is required

locate it at the origin: For ease of operation, we recommend that you convert LayoutRoot into a Canvas control. Why do you want to place roles like this? You need to understand the Silverlight container concept. The position of the control is located in the upper left corner, this has the same relationship with the screen, so we can align future controls directly with the Center of the role ). The following is the time to test the capabilities of art design. Our goal is as follows: Don't be f

Hdu 2842 (Rapid matrix power + recursion), hdu2842 A Chinese ring game has n rings on a wooden stick. The first ring can be placed or removed at will, the rest of the ring x if you want to put or remove must be the first ring X-1 is placed and the first X-2 ring is all removed, ask n rings at least how many operations can be all removed.Problem: recurrence is required. First, the first step must be to remo

Test instructions: For a given two rings, find the area where two rings intersect.Idea: Because the center and RADIUS are not the same, divided a lot of situations, and later found that as long as the two circle of the function of the intersection can not be so complicated after writing. The template for the area where two circles intersect is as follows:DoubleArea_of_overlap (Point C1,DoubleR1, point C2,Do
