In this simple exercise, you will create a program that will take two lists of integers, a and b. Each list will
consist of 3 positive integers above 0, representing the dimensions of cuboids a and b. You must find the difference
of the cuboids' volumes regardless of which is bigger.
For example, if the parameters passed are ([2, 2, 3], [5, 4, 1]), the volume of a is 12 and the volume of b is 20.
Therefore, the function should return 8.
Your function will be tested with pre-made examples as well as random ones.
If you can, try writing it in one line of code.
def find_difference(a, b)
(a.inject(:*) - b.inject(:*)).abs
end
