Design and implement a Version-Queue data structure. A Version-Queue maintains a version number along with normal Queue functionality. Every operation [Enqueue/Dequeue] on the Queue increments its version. Implement the following functions: 1. Enqueue - appends an element at the end of the queue. 2. Dequeue - returns the front element of the queue. 3. Print - it takes a version number as input and prints the elements of the queue of the given version. The version number input can also be an old/historical version number. E.g. if the current version number of the queue is 7 and the input to this function is 5, then it should print the elements of the queue when its version number was 5

Implement STAQUE, an abstract data type that combines a linked stack with a linked queue. Create methods that conduct insert and delete operations on a non-empty STAQUE, referred to as PUSHINS and POPDEL, respectively.POPDEL deletes entries from the top/front of the list, whereas PUSHINS inserts an element at the front or back of the STAQUE based on an indication supplied to the operation.
