Question

By adding an extra data member to the priority queue class in Exercise 27, you can implement both insert and findMin in constant time. The extra data member maintains the array position where the minimum is stored. However, deleteMin is still expensive. Do the following: a. Describe the algorithms for insert, findMin, and deleteMin. b. What is the Big-Oh running time for deleteMin? c. Write an implementation that uses these algorithms.
