Now we encounter the problem based on the basics of c++ ; "we can't use datastructures or any arrays".

so I get the code

CODE :

include

include

using namespace std;

int main() { // Complete the code. int n,m;

cin>>n>>m;
// cout<<n<<m;
for(int i=n;i<=m;i++){
    if(i==1){
        cout<<"one"<<"\n";
    }
    else if(i==2){
        cout<<"two"<<"\n";
    }
    else if(i==3){
        cout<<"three"<<"\n";
    }
    else if(i==4){
        cout<<"four"<<"\n";
    }
    else if(i==5){
        cout<<"five"<<"\n";
    }
    else if(i==6){
        cout<<"six"<<"\n";
    }
    else if(i==7){
        cout<<"seven"<<"\n";
    }
    else if(i==8){
        cout<<"eight"<<"\n";
    }
    else if(i==9){
        cout<<"nine"<<"\n";
    }
    else if(i>9){
        if(i%2 ==0){
            cout<<"even"<<"\n";
        }
        else{
            cout<<"odd"<<"\n";
        }
    }
}
return 0;

}

}
