using namespace std;

int main() {

    int n;                                                         //Size of array
    cin>>n;             
    
    int a[n];                                               //array declaration
    
    for(int i=0;i<n;i++){                       //reading array
        cin>>a[i];
    }
    
    for(int i=0;i<n;i++){                           //loop to access each element of array
        if(a[i]%2==0){                             //if the array element is even print it
            cout<<a[i]<<" ";
        }
    }
