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.

[12, 0, -56, 88, -86, -56, 88, 0, 68, 37, -12]
[12, 56, 144, 174, 30, 144, 88, 68, 31, 49]

[-17, -44, 39, -40, -41, -57]
[27, 83, 79, 1, 16]

[-9, 10, 56, 0, 55, 44]

[19, 46, 56, 55, 11]
