#include <bits/stdc++.h>

using namespace std;

string re(long long c, long long d,string x){
    string y="";
    for(long long i=d; i>=c; i--) y=y+x[i];

    long long t=0;
    string res="";
    for(long long i=0; i<x.size(); i++){
        int q=(int)x[i];
        if(q<65||(q>90&&q<97)||q>122){

            res=res+x[i];
            t=i+1;
        }
    }
    res=res+re(t,x.size()-1,x);
    return res;

int main()
{
    while(getline(cin,a)){
        istringstream iss;
        iss.clear();
        iss.str(a);

        cout<<endl;

}

In the end you write empty line. You must delete your last cout.

Thanks you. But I repaired and still WA#1

Try next tests(be attentive to the newline and whitespace):
