SAS INTERVIEWS CONCEPTUAL QUESTIONS XIV

WE HAVE TWO SAS DATA SETS:



Data one;
drop i j;
array a[60];
array b[60];
do j=1 to 1000;
do i=1 to 60;
a[i]=int(ranuni(i+j)*10);
b[i]=int(ranuni(j)*10);
end;
output;
end;
run;


Data two;
drop i j;
array a[60];
array b[60];
do j=1 to 1000;
do i=1 to 60;
a[i]=int(ranuni(i+j)*10);
b[i]=int(ranuni(j)*10);
end;
output;
end;
run;


WE HAVE TO CREATE A SAS DATA SET "THREE" THAT SHOULD HAVE DIFFERENCE OF THE COMMON VARIABLES OF DATA SETS "ONE" AND "TWO".
