汇编语言是直接在硬件上工作的编程语言,由以下3类指令组成:
- 汇编指令:机器码的助记符,有对应的机器码
- 伪指令:没有对应的机器码,由编译器执行

感谢ftiasch老师教导,参考了 https://async.icpc-camp.org/d/408-fft 和其他一些地方的东西 | |
P = 1e9+7 | |
Q = ceil(sqrt(P)) | |
a, b为两个向量 | |
c = convolution(a, b) | |
c系数取值为 [0, n*(P-1)^2] 的整数,若n*(P-1)^2的表示需要超过53 bits(double mantissa)则很可能会出错 |

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.
After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

国内从 Docker Hub 拉取镜像有时会遇到困难,此时可以配置镜像加速器。Docker 官方和国内很多云服务商都提供了国内加速器服务。
