Maximum difference between adjacent elements of list
Maximum difference between adjacent elements of list is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

- Find maximum difference between adjacent elements of list.

- Output:
working... Maximum difference between adjacent elements of list is: Input list: [-3,0,1,1,-2.3,0,5.5,8,6,2,9,11,8,1] Output: 2,9 ==> 7 8,1 ==> 7 done...
