如何使用 C++ 构建一个环结构？

C++ 环状移动

#include <iostream>
#include <list>

int main() {
    auto list = std::list<int>{1, 3, 5, 7, 9};
    for (auto i = 0; i < 16; i++) {
        std::cout << list.front() << std::endl;
        list.splice(list.end(), list, list.begin());
    }
    std::cout << "==============================" << std::endl;
    return 0;
}

输出

1
3
5
7
9
1
3
5
7
9
1
3
5
7
9
1
==============================
