Interview Question to my friend.
x=A,B,C,D,E,F,G ;
He wants to find 4th comma or 5th comma.
I have given this answer.
data a;
x='A,B,C,D,E,F';
run;
%let p=9;
data find_comma;
set a;
fouth_comma=find(x,',',&p);
run;
Is it correct? or wrong?
Interview asked me to write dynamically.
Please correct if I'm wrong.
They want dynamically?
data _null_;
x='A,B,C,D,E,F';
n=4;
call scan(x,n,p,l,',');
position=p+l ;
putlog 'n=' n 'position=' position;
n=5;
call scan(x,n,p,l,',');
position=p+l ;
putlog 'n=' n 'position=' position;
run;
Hello,
data _null_;
x='A,B,C,D,E,F';
do n=4, 5;
position=length(prxchange(cats('s/^(([^,]*,){',n,'}).*$/$1/'),1,x));
put n= position=;
end;
run;
