如何在STL容器内移动元素

#include<iostream>
#include<vector>
#include<algorithm>

int main() {
    std::vector<int> v = {1, 2, 3, 4, 5};
    std::move(v.begin() + 1, v.begin() + 4, v.begin() + 2);
    for (int i : v) {
        std::cout << i << " ";
    }
    return 0;
}

#include<iostream>
#include<vector>
#include<algorithm>

int main() {
    std::vector<int> v = {1, 2, 3, 4, 5};
    std::rotate(v.begin() + 1, v.begin() + 3, v.end());
    for (int i : v) {
        std::cout << i << " ";
    }
    return 0;
}
