Topic Link: Click to open the link;Test instructions: Given two line segments, one segment endpoint is a, B, and the other segment endpoint is c,d, at different speeds on two segments and not on the segment, to find the shortest time.Analysis: The subject a total of three time, on a-B, on the c-d, in the blank place. The three time period is x, Y, Z. Then once the X and Y are determined, Z can be determined, because the points on the two segments are determined, Z is also found, if x determines

HDU 3400 line belt (three minutes and three minutes) ACM Question address:HDU 3400 line belt Question:It is to give you two line segments AB and CD. A person runs P at the speed of AB, Q at the CD, and R at the speed of other places. Ask you the minimum time from A to D. Analysis:First, the point on the Three-Point AB, and then the point on the Three-Point CD.Proof:Set e to AB and F to CD.The time spent on

Question Link Well, there is a quality three-point question, which belongs to the nested three-point question. After thinking about this question for a long time, I only wrote several independent equations. Let's look at the solution report. Then, I

Two parallel lines, AB, CD, and AB, are given. The speed of CD is Q, and the line segment is R. How long is the shortest time from A to D? Method: 3 points. After a simple analysis, we found that this function is a single-peak function, which is

I. Introduction Segmentation fault occurs when you use Android pre-installed gdbserver to debug the dynamic library. You have to use the existing compilation chain to re-compile a gdbserver. Thanks to Android-How-to rebuild gdbserver this article, refer to this article my solution process is as follows. Here we should emphasize one point:The following is the target path of sysroot during sysroot compilation and the sysroot path specified during gdbserver compilation. You must use the [absolute p

switch kernel becomes a bottleneck for performance implementation; the second is the cross-bus structure. It can establish direct point-to-point connections between ports, which is good for single-point transmission performance, but not suitable for multi-point transmission. The third is the hybrid cross-bus structure, this is a hybrid cross-bus implementation method. Its design idea is to divide an integrated cross-Bus Matrix into small cross matrices and connect them through a high-performanc
