compare the data

Hi Team,

I have dataset with data this way

data dataset1;

input v1 v2;

cards;

10 12

12 21

23 22

22 45

33 24

; run;

And I am expecting the output which would diagonally compare and provides me the max value .. if diagonally value was not found then it should return the same value with the column v2 (33 24 seen below)

output:-

V1 V2

10 21

23 45

33 24

Any help on this is really appreciated..
