基数排序

众所周知我是一个卡常狂魔其实是因为算法太差干不过机房其他大佬所以才卡常的所以平时也有了解一些比较玄学的算法这其中就包括基数排序和手动Ofast，指针，循环展开，寄存器，快速IO，fread，fwrite

gcc 中-O -O1 -O2 -O3 -Os -Ofast -Og优化的原理

一般来说，如果不指定优化标识的话，gcc就会产生可调试代码，每条指令之间将是独立的：可以在指令之间设置断点，使用gdb中的p命令查看变量的值，改变变量的值等。并且把获取最快的编译速度作为它的目标。当优化标识被启用之后，gcc编译器将会试图改变程序的结构（当然会在保证变换之后的程序与源程序语义等价的前提之下），以满足某些目标，如：代码大小最小或运行速度更快（只不过通常来说，这两个目标是矛盾的，二者不
