Design a data structure to support the following two operations for a dynamic multiset S of integers, which allows duplicate values: INSERT(S, x) inserts x into S. DELETE-LARGER-HALF(S) deletes the largest |S|/2 elements from S. Explain how to implement this data structure so that any sequence of m INSERT and DELETE-LARGER-HALF operations runs in O(m) time. Your implementation should also include a way to output the elements of S in O(|S|) time. (solve it using the accounting method)
