Define a min-max queue to be a data structure that supports the queue operations of enqueue() and dequeue() for objects that come from a total order, as well as operations min() and max(), which return, but do not delete the minimum or maximum element in the min-max queue, respectively. Describe an implementation for a min-max queue that can perform each of these operations in amortized O(1) time.
