"Music Your Way" Kattis

Problems and Contests
#1

Hello everybody
I’m trying to solve the Kattis problem “Music your Way” Music Your Way but in the third test I receive a wrong answer. I would be very grateful if you can help me to know what is my mistake to keep improving. The code is pasted below. Thanks :slight_smile:

#include <bits/stdc++.h>

using namespace std;


typedef vector< vector<string> > vs;
vector <string> comandos;
string cadena;

bool cmp(vector<string> a, vector<string> b){
    int pos;
    for(int i=0; i<comandos.size(); i++) {
        if(comandos[i]==cadena) {
            pos=i;
            break;
        }
    }

    return a[pos]<b[pos];
}

int main(){

    int m, n, cont=0;
    char aux;
    cadena="";
    while(cin.get(aux) && aux!='\n'){
        if(aux!=32) cadena+=aux;
        else{
            comandos.push_back(cadena);
            cadena="";
        }
    }
    comandos.push_back(cadena);
    cin>>m;
    cin.ignore();
    vs canciones (m, vector<string>(comandos.size()));
    for(int i=0; i<m; i++){
        for(int j=0; j<comandos.size(); j++){
            cin>>canciones[i][j];
        }
    }
    cin>>n;
    cin.ignore();
    while(n--){
        if(cont!=0) cout<<"\n";
        cont++;
        vs vaux=canciones;
        cin>>cadena;
        stable_sort(vaux.begin(), vaux.end(), cmp);
        cout<<comandos[0];
        for(int i=1; i<comandos.size(); i++) cout<<" "<<comandos[i];
        cout<<"\n";
        for(int i=0; i<m; i++){
            for(int j=0; j<comandos.size(); j++){
                cout<<vaux[i][j];
                if(j!=comandos.size()-1) cout<<" ";
            }
            cout<<"\n";
        }
    }


return 0;
