Other good things
Questions
Lab
When implementing set with previous, you may find it useful to
have a variable that keeps track of the index of the element to set
or remove. (Set it to something like -1 or Int.MIN_VALUE if you can’t
set or remove.)
Writeup: Exercise 6b
Debrief
Moral: Adding and removing elements is likely to be expensive. So
be careful about using ArrayLists when you need an expandable list.
