/* Program 41
Write a complete Java program that invokes a function satis() to find whether four integers a, b, c, d sent to satis() satisfy the equation 3a + 3b + 3c = 3d or not. The function satis returns 0 if the above situation is satisfied with the given four numbners and returns -1 otherwise.
