this have far can't figure out last part appreciated

void findpattern(int score1, int score2, int score3) {    if (score1 == score2 && score1 == score3 && score2 == score3 )    {       cout << "all 3 scores same" << endl;    } else if (score1 < score2 && score2 < score3) {       cout << "the scores going steadily upward" << endl;    } else if (score1 > score2 && score2 > score3) {       cout<<"the scores going steadily downward"<<endl;    } else if(score1 < score2 && score2 > score3) {       cout << "the scores first went up, went down" << endl;    } else if (score1 > score2 && score2 < score3) {       cout<<"the scores first went down, went up"<<endl;    } 

else if ( ( ( score1 == score2 ) && score2 != score3 ) || ( ( score2 == score3 ) && ( score2 != score1 ) ) )     cout << "two scores equal" << endl;
