#include <iostream>

    int courseGrades[num_val];
    int i;
    courseGrades[0]=7;
    courseGrades[1]=9;
    courseGrades[2]=11;
    courseGrades[3]=10;
    for(i=0;i<num_val;++i){
        cout<<courseGrades[i];
        if(i!=num_val-1){
            cout<<" ";
        }
    }
     cout << "\n" ;
     for(i=num_val-1;i>=0;--i){
        cout<<courseGrades[i];
        if(i!=0){
            cout<<" ";
        }
    }
    cout << "\n";
    return 0;
