Write a static method called sameGap that takes an array of integers as a parameter and that returns whether or not the gap between consecutive values in the array is always the same. The gap between consecutive values is defined to be the absolute value of the difference between the two values. For example, consider the following array:
[1, 4, 7, 10, 13, 10, 13, 10, 7, 4]
Each consecutive pair of values has a gap of 3. The first pair of values is 1 and 4, which are 3 apart. The second pair of values is 4 and 7, which are 3 apart. The third pair of values is 7 and 10, which are 3 apart.
