Suppose the following operations are performed on an empty queue:enqueue(5);enqueue(?);dequeue();enqueue(9);enqueue ( 12);dequeue();enqueue(10);Insert numbers in the following diagram to show what will be stored in the staticqueue after the operations have executed .front rear

Problem 7: Assume that a queue class called XQueue has a no argument constructor, an enqueue() method, a dequeue() method and an isEmpty() method. Write a method that merges two given queues by copying the elements in an alternating sequence and returning the resulting combined queue. Note: make sure that you don't include unnecessary spaces in your answer! public XQueue merge(XQueue q1, XQueue q2) { XQueue neWQueue = new XQueue(); while (!q1.isEmpty() && !q2.isEmpty()) { newQueue.enqueue( #01 ); newQueue.enqueue( #02); } while (!q1.isEmpty()) { #03 ; } while (!q2.is Empty()) { #04 ; } return newQueue (); }

Algorithms in pseudo code **MUST** be placed in code blocks/fences, and use `cpp` as the syntax highlighter. - Algorithms should follow the pseudo code standard described in *Pseudocode Handout*. - Do NOT change the template except the answer portion. Formulas and equations should be in math mode using Latex math symbols. - Markdown math tutorial: http://tug.ctan.org/info/undergradmath/undergradmat h.pdf - Two ways to enter math mode: - Insert a pair of dollar signs: \$your equations go here\$. This is the inline math mode. *Notice that there is no space between the \$ and the letter*. - Insert a pair of double-dollar signs: \$\$ your equations go here \$\$, which produces a standalone equation/formula set. le for sub
