Как распечатать массив на основе результата, который я хочу? Row by Row

Question

Мне нужна помощь для распечатки массивов по строкам, но это 2 разных массива ...

В настоящее время мои коды позволяют мне печатать все имена, следить за результатами, следовать по средним баллам и сортам. Однако я должен был бы выводить их на основе имени студента и оценка .. Посмотрите на картину, например ...

Текущая ситуация: Current

Ожидаемый выход ..: Expected

For i=0 till names.length 
    print names[i] 
    total=0 
    For j=0 till scores[i].length 
     print scores[i][j] 
     total=total+scores[i][j] 
    End For 
    Print Average = total/scores[i].length; 
    decide Grade on basis of average and print 
End For
