((by C++ ))Write a program that will reverse the content of a Queue using the following standard queue operations.
- enqueue(x) : Add an item x to rear of queue.
- dequeue() : Remove an item from front of queue.
- empty() : Checks if a queue is empty or not.
For reversing the queue one approach could be to store the elements of the queue in a temporary data structure in a manner such that if we re-insert the elements in the queue they would get inserted in reverse order. So now our task is to choose such data-structure which can serve the purpose. According to the approach, the data-structure should have the property of LIFO as the last element to be inserted in the data structure should be the first element of the reversed queue. Using the new data structure to store the elements of the queue temporarily should:
- Pop the elements from the queue and insert into the new data structure. (first element of the data structure is last element of the queue)
- Pop the elements of the data structure to insert back into the queue. (The last element of the data structure is the first one to be inserted into the queue)
Input Format
The program should accept N series of integer values where 1 < N < 10 separated by a space and stored in a queue. If the input N integer exceeds the allowed number of input the program should display an error message.
Example Input
Enter N Integer values: 1 2 3 4 5 6 7 8 9 10 |
Output Format
The program should display the reverser order of the queue elements in a single line separated by a space. (Note: that only queue standards operations can be used to display the queue elements).
Example Output
Reverse Queue: 10 9 8 7 6 5 4 3 2 1 |
