Hi Jonas,
Depends on what we're trying to do. Is it necessary to have a nested loop
here? What kind of problem is this trying to solve?
If the question is: "are any elements in list_a shared in list_b?", then
yes, we can avoid nested loops altogether. If we're concerned about
efficiency, we can take advanatage of dictionaries, or use something like
the 'set' data structure.
