Question 6

Which of these statements are true about a standard TreeMap?

Group of answer choices

they have two generics (type parameters)

as with all maps, they map Keys to Values

their generics are often called K (for "key") and V (for "value")

since they are implemented with a BST, they automatically maintain ordering

they can be used to implement an Index concept, where Values are always integers

O(n) to O(log n)

O(log n) to O(n)

O(log n) to O(n log n)

True

False

Question 10
