Given two queue, you need to combine them to create a single queue. To be fair to all customers that are in the queue, you need to alternate between the two queues in adding them to the single queue. Hint: The queues may not be the same length, so one queue may finish before the other one. queue int> combineQueues (queue int>& qa, queue int>& qb) { // YOUR CODE GOES HERE }
