And of course there is the inevitable naming bikeshed for the elements:
(a, b)
(first, second)

What's the fastest algorithm for sorting a linked list?
... data is a comparison sort of an almost sorted list with k elements out of order. This can be sorted in O ( kn ) operations.
Copying the list to an array and back would be O(N), so any sorting algorithm can be used if space is not an issue.
For example, given a linked list containing uint_8, this ...

How to get all subsets of a set? (powerset)
...deally a set) into a list because by a set is a data structure of unique unordered elements, and the order will be crucial to generate the subsets.
