使用istringstream和istream_iterator颠倒句子中的单词

#include <iostream>
#include <sstream>
#include <iterator>
#include <vector>
#include <algorithm>

std::string reverseSentence(const std::string& sentence) {
    std::istringstream iss(sentence); // 创建istringstream对象
    std::vector<std::string> words; // 存储单词的容器

    // 使用istream_iterator遍历单词并存储
    std::copy(std::istream_iterator<std::string>(iss), std::istream_iterator<std::string>(), std::back_inserter(words));

    // 反向遍历容器，构建颠倒顺序的句子
    std::string reversedSentence;
    for (auto it = words.rbegin(); it != words.rend(); ++it) {
        reversedSentence += *it;
        if (it != words.rend() - 1) {
            reversedSentence += " ";
        }
    }

    return reversedSentence;
}

int main() {
    std::string sentence = "This is a sample sentence"; // 待颠倒的句子
    std::string reversed = reverseSentence(sentence); // 颠倒单词顺序

    std::cout << reversed << std::endl; // 输出颠倒顺序的句子

    return 0;
