reverse(v.begin()+5,v.begin()+8); Inthe abovefunction,input we have applied reverse()on the vector fromindex5to index7. Thereforewhenwe display the vector wegetreverse order fromindex5to index7. CPP实现 // CPP program to illustrate // std::reverse() function of STL #include<algorithm> ...
reverse函数是一个就地(in-place)算法,它不需要额外的存储空间来存储反转后的元素。因此,其空间复杂度为O(1)。 5. 代码示例 下面是一个使用reverse函数的示例代码: cpp #include <iostream> #include <vector> #include <algorithm> // 包含reverse函数的头文件 int main() { std::ve...

看cplusplus和cppreference的上的解释 Notice however that when an iterator is reversed, the reversed version does not point to the same element in the range, but to the one preceding it. This is so, in order to arrange for the past-the-end element of a range: An iterator pointing to a ...
