Given two sorted positive integer arrays A(n) and B(n), we define a
set S = {(a,b) | a in A and b in B}. Obviously there are n2 elements
in S. The value of such a pair is defined as Val(a,b) = a + b. Now we
want to get the n pairs from S with largest values. need an O(n)
algorithm.

Regards,
@Mac: It gives us the first largest pair but need not all n pairs ..
ex:
A=1 1 3 4
B=1 2 3 4
pairs : (4,4),(4,3),(3,3),(2,4) .

since its sorted , cant we just take last (largest if assedning) elements
of each and return o(1)
@bharat I think pair of your example would be (4,4) , (4,3) ,(3,4),
(3,3)
correct me if am wrong..
