Write and test a method that takes any array of integers and returns a 2-dimensional array containing all the successive differences. (30 points)

E.g. Initial array = {2, 9, 28, 65, 126} Returned array is shown below. (How the elements are computed is shown to the right of each row.)

2 9 28 65 126

7 19 37 61

12 18 24

6 6

0

7 = 9-2 19 = 28-9 37 = 65-28 61 = 126-65 12 = 19-7 18 = 37-19 24 = 61-37 6 6 6 = 18-12 6 = 24-18 0
