I R-6.7 What values are returned during the following sequence of queue operations, if executed on an initially empty queue? enqueue(5), enqueue(3), dequeue(), enqueue(2), enqueue(8), dequeue(), dequeue(), enqueue(9), enqueue(1), dequeue(), enqueue(7), enqueue(6), dequeue(), dequeue(), enqueue(4), dequeue(), dequeue(). R-6.5 Implement a function that reverses a list of elements by pushing them onto a stack in one order, and writing them back to the list in reversed order. C-6.20 Describe a nonrecursive algorithm for enumerating all permutations of the numbers \{1,2,..., n\} using an explicit stack.
