题解 | #编写函数实现字符串翻转（引用方式）#

#include <algorithm>
#include <any>
#include<bits/stdc++.h>
using namespace std;
// write your code here......
void reverse(string &s);

int main(){
    string s;
    getline(cin,s);
    // write your code here......
    
    reverse(s);

    cout<<s;
    return 0;
}

void reverse(string &s)
{
    for (int i = 0; i < s.size() / 2; ++i)
        swap(s[i], s[s.size() - 1 -i]);
}

void swap(int &m, int &n)
{
    int temp = m;
    m = n;
    n = temp;
}

按照题目使用引用进行转换
