#include <algorithm> algorithm algorithmalgorithm头文件里面包含了很多十分实用的函数,至少于我而言,这是我用的最多的stlstl。由于所有对区间进行操作的函数都遵循左闭右开的原则,所以假设操作区间为[l,r],那么写在函数里的应该是[l,r+1]。 reverse

把尖括号换成双引号就可以了。 查了一下两者的区别: 尖括号#include <>表示系统预定义的文件 双引号#include "" 表格用户自定义的文件 此处因为des.h是本地从源码编译的,因此作为用户自定义文件,要用双引号include。 参考:Difference between #include and #include" " in C/C++ with Examples - GeeksforGeek...
