Question: Suppose we wish to support a new method countRange(k 1 , k 2 ) that determines how many keys of a sorted map fall in

Suppose we wish to support a new method countRange(k₁, k₂) that determines how many keys of a sorted map fall in the specified range. We could clearly implement this in O(s + h) time by adapting our approach to subMap. Describe how to modify the search-tree structure to support O(h) worst-case time for countRange.
