Write a program to evaluate the function f (x, y) for any two values x and y, where the function f (x, y) is defined as follows; f (x, y) = x+y if x and y are greater than or equal to 0, f (x, y) = x+y^2 if x is greater than or equal to 0 and y is less than 0, f (x, y) = x^2+y if x is less than 0 and y is greater than or equal to 0 and f (x, y) = x^2+y^2 if x and y are less than 0.
