The main topic: give you n points, calculate how many acute triangle. Number of acute triangle = (number of acute angles in figure-Blunt right angle number)/3 There are several blunt right angles, acute angles in the calculation diagram. Enumerates the vertices of a corner, and then enumerates the edges that the vertex leads to, which can be represented by a vector. These vectors are sorted in polar order, enumeration of the starting edge, the method

amplification Analysis of double buffering class time calculation problem @ (OS) An OS uses double buffering to transfer data on disk. The time it takes to transfer data from disk to the buffer is T1, and the time it takes to transfer data from the buffer to the user area is T2 (assuming T2 is much smaller than T1,T3). The amount of time that the CPU takes to process the data is T3, and the total time used for the system is to repeat N times: (n−1) X

I. Loss of precision in floating-point calculationsProbably a lot of friends with programming experience are not familiar with this problem: no matter what programming language you use, when you use floating-point data for accurate calculations, you may encounter errors in the calculation results. Take a look at the following example.This is an example of a result error when using floating-point data for precise calculations, written in Java, omitted.
