What is list intersection?

List intersection returns only items that appear in BOTH lists. If List A is [apple, banana, cherry] and List B is [banana, date, cherry], the intersection is [banana, cherry].

What is list difference?

List difference (A minus B) returns items in List A that do NOT appear in List B. If A is [apple, banana, cherry] and B is [banana, date], A − B is [apple, cherry].
