You have reached the end of the Hash Table chapter. This checkpoint tests what you can apply: how a key becomes an index, what happens when two keys collide, the two families of collision resolution and what each costs, load factor and rehashing, how to judge a hash function, and the reasoning behind the five problems you solved. The pool holds 24 questions and serves 12 per attempt, mixed across easy, medium, and hard. Use the hint if you get stuck, and read the explanation on every option, including the ones you did not pick.
