In this task you are given a list of integers and you need to find the absolute value of the difference between each two consecutive values. The output should be a list of the absolute value of the differences of each two consecutive values.
One example is below.
Q: [7, 1, 5, 8, -4]
A: [6, 4, 3, 12]
Rationale: The output is a list of the absolute value of the differences of every two consecutive values. So this is a good example.
