-> 挑战二:写一个程序,运行该进程时,你计算机每一个核的 CPU 占用率是各不相同的有规律的曲线
-> 示例效果如:
-> ![sample](sample.jpg)
-
-Translation: Write a program and make each core of your CPU get a different but regular usage rate graph.
-
-Code is in `main.cpp`. Remember to not compile it with O2 optimization, or my loop will be eliminated.
