| 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 |

GNOME's tracker is a CPU and privacy hog. There's a pretty good case as to why it's neither useful nor necessary here: http://lduros.net/posts/tracker-sucks-thanks-tracker/
After discovering it chowing 2 cores, I decided to go about disabling it.

In general, check the crt/host_config.h file to find out which versions are supported.
Sometimes it is possible to hack the requirements there to get some newer versions working, too :)
