Just take the matrix. for 2 point to be saddler the conditions specified will say this. suppose u have two points of a column as saddler point i.e. q and p .
if u consider 1 as saddler point then it's u must be saying that q>p
while if u have to say 2 also sadller point q<p . only one can happen at a time . make other case yourself and u wll get this .
5 4 3
6 3 2
7 2 1
only 5 is sadler point as considering 6 should say that 6 should be least but 5 is least .
