6)What is an activation record? 7)What elements are included in a method’s local environment? 8)What are the two base cases for a recursive binary search algorithm? 9)When is the base case first > last (where first is the index of the first item in the array and last is the index of the last item in the array) reached in a recursive binary search algorithm? 10)When is the base case value == anArray[mid] (where mid is the midpoint of the array) reached in a recursive binary search algorithm?
