Lester is very intent on finding a formula to calculate the difference between two squares but doesn't have any squared terms in it.
Eg: If x and y are two numbers with y>x then he wants to find a formula to calculate (y^2)-(x^2) which does not contain any x^2 or y^2 terms in it.

He finds that there are two cases:
a) when x and y are consecutive.
b) when x and y are not consecutive.

Can you help him find the formula?
