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.

[20, -64, -71, 89, 51, 86, 55, 58, 45, 13, -97, 31, -77]
[84, 7, 160, 38, 35, 31, 3, 13, 32, 110, 128, 108]

[42, -94, -85, -77, 91, -90, -70, 52, 21, 46, -13, -60, -17]
[136, 9, 8, 168, 181, 20, 122, 31, 25, 59, 47, 43]

[-31, -55, 26, -17, -6, -56, -51, 40, 71, 2, 41, -90, -100, -63]

[24, 81, 43, 11, 50, 5, 91, 31, 69, 39, 131, 10, 37]
