Answer:
Explanation:
a)
our first step will be at (2,2) so we will only remain with
one row (1,1),(1,2)......(1,n) and
one column (1,1),(2,1),...(n,1).
when the other player choses one of these remaining options then chose symetrically opposite one
choosing one element in a row doesnot eat an element in column and visaversa
that is if he chooses (i,1) you choose (1,i) or if he chooses(1,i) you choose (i,1). in your following steps.
finally he choose (1,2) you choose (2,1) then he remains with (1,1) and he looses
or finally if he choose (2,1) you choose (1,2) then he remains with (1,1) and he looses
so we wins if we start.
b). here in this gumdrop we are fixing where red one is, if it is some where else there might not be an optimal strategy.
