Assertion (A): Every positive integer that cannot be written in the form \(4k+2\) can be expressed as the difference of two squares. Reason (R): Because \(m^2-n^2=(m-n)(m+n)\), and both the factors on the right-hand side always have the same parity (both odd or both even). Choose the correct option with reference to the above:

Positive integers \(m>n\) are such that \(m^2-n^2=360\). How many such pairs \((m,n)\) are there?

If \(m,n\) are positive integers and \(m^2-n^2=945\), then how many such pairs \((m,n)\) are there?
