" 8.10 Suppose we want to add an extra operation, deunion, which undoes the last union operation that has not been already undone. Show that if we do union-by-height and finds without path compression, then deunion is easy, and a sequence of M union, find, and deunion operations takes O(M logN) time. Why does path compression make deunion hard
