STL之rotate STL对左旋转字符串针对三种不同数据结构进行了不同的实现。 对单向链表采用的是同步位移,双向链表是三次翻转,都很简单,主要看看针对随机存取的数组做的循环位移实现。 STL这个版本的源码如下: [cpp] view plain copy template <class RandomAccessIterator, class Dista... ...
std::vector<int> v; std::vector<int> v2; for (int i = 0; i < 10; ++i) v.push_back(i); for (int i = 0; i < 10; ++i) v2.push_back(i); std::rotate(v.begin(), v.begin() + 4, v.end()); std::rotate(v2.begin(), v2.begin() + 4, v2.begin() + 5); ...
My knowledge of cpp is limited, but perhaps utilizing a char array could be a solution. Solution 1: I recommendstd::rotate: std::rotate(s.begin(), s.begin() + 1, s.end()); Solution 2: This approach moves the initial character to the end of the string, resembling a solitary cycle...
https://oj.leetcode.com/problems/find-minimum-in-rotated-sorted-array/ Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e.,0 1 2 4 5 6 7might become4 5 6 7 0 1 2). Find the minimum element. You may assume no duplicate exists in the array. 解题...
C++：尝试使用std：：rotate和fftw_complex数据时产生错误：“数组必须用大括号括起的初始值设定项初始化”std::complex：对于类型为std::complex<T>的任何对象z，reinterpret_cast<T(&)[2]>(z)[0]是z的真实的部，reinterpret_cast<T(&)[2]>(z)[1]是z的虚部。此要求的目的是保持C++库复数类型和C语言...
