Urgent please help 1. Suppose we have a queue q (from front to rear: 2, 4, 6, 8, 10) and an initially empty stacks. We dequeue the elements of q one by one and push them onto s, until q becomesempty. Next, we pop the elements of s one by one and enqueue them in q, until s becomesempty. How does q now look like (from front to rear)?a. 6, 4, 2, 8, 10b. 2, 6, 4, 10, 8c. 10, 8, 6, 4, 2d. 2, 4, 6, 8, 10a2. Consider an implementation of Queue based on circular arrays. Suppose that we set themaximum queue capacity to 5, that is, MAX_QUEUE_SIZE=5. In other words, theunderlying array will have 5 elements, indexed 0, 1, 2, 3, 4. We define queue as follows:Circular Array Queue queue = new Circular ArrayQueue0;Assume that the front variable in queue is initially set to 0, as shown below.front initiallyset to position 0234,6₂8310234,6,8,102,4,6,8,102a.
