如何在C++中从字符串的两个向量创建一个字符串？

#include <iostream>
#include <vector>
#include <string>

std::string createStringFromVectors(const std::vector<char>& chars, const std::vector<int>& indices) {
    std::string result;
    for (int i : indices) {
        result += chars[i];
    }
    return result;
}

int main() {
    std::vector<char> chars = {'H', 'e', 'l', 'l', 'o'};
    std::vector<int> indices = {0, 2, 4};

    std::string str = createStringFromVectors(chars, indices);
    std::cout << str << std::endl;

    return 0;
}
