    Trophy Points:
    template < class Object>
    void fix(queueType < Object> &q, int n)
    if (n>=1)

    Object temp = q.front();


    (a)what will the final state of queue q1 be after the statement fix(q1,2); is exexuted, if q1 has the values (1,2,3,4,5}

    my answer: {2,3,4,5,1} because q.addQueue adds an element at the back
    step 1: if (2>1) true
    step 2: element {1} added to temp
    step 3: q.deleteQueue(); deletes element{1}
    step 4: fix(q1, 2-1)
    step 5: q.addQueue(temp); element{1} is added at the back of the queue

    (b) what does function fix() do?

    It restores the deleted element at the end of the queue

    (c) A precondition for fix() is: The queue exists and it is not empty

    What do u think? Are my answers correct?
