Our goal is to write a text$-$based version of the board game Snakes and Ladders. In Snakes and Ladders, players advance through a mostly$-$linear arrangement of spaces from start to finish, except some spaces contain snakes, which move the player back to an earlier space, and some contain ladders, which move the player forwards to a later space. In addition to snakes and ladders $($we will call these both $$paths$$ to other spaces$),$ we will also have $$expanding$$ spaces that will add new spaces in front of or behind the player who lands on them. We will implement this game using our dynamic ArrayList class. Rather than make a single hard$-$coded board for the game, we will write functionality to procedurally generate each board. a$.$ Begin by writing out the dynamic ArrayList class found in the notes, implementing the provided List interface. Note that List extends Iterable and so you will need to include an iterator. You do not need to include an Iterator remove$()$ method. b$.$ Create a class SnakesLaddersBo
