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.

[-30, 87, 93, 56, -34, 29, 37, 99, -72, -85, -60, 61]
[117, 6, 37, 90, 63, 8, 62, 171, 13, 25, 121]

[91, 20]
[71]

[-26, -49, -73, -48, -59, -13, 76, -40, -100, 2, 79]

[23, 24, 25, 11, 46, 89, 116, 60, 102, 77]
