输入一个整数，将这个整数以字符串的形式逆序输出

#include<iostream>#include<string>#include<sstream>using namespace std;int main(){ int input; stringstream ss; string res; while (cin >> input) { while (input / 10 != 0) { ss << input % 10; input /= 10; } ss << input % 10; ss >> res; cout<<res; } return 0;}</sstream></string></iostream>
