Given the following code fragment: String str = "practice makes perfect"; Queue stringQ = new Queue () ; Queue spaceQ = new Queue(); for (int i = 0; i= 'a'&& str.charAt(i) <= 'k') Draw two queue diagrams to represent stringQ and spaceQ elements after the code fragment has been executed. Label the diagrams with front and rear of the queues.
Consider the following structure of a node for a linked list. struct Node { int key; Node *next; }; What will be the output of the following pseudo-code? Assume, head is a pointer to the first node of the following linked list. 5->2->8->2->9->2->11-> NULL Node *pres head; 0; while(pres!= NULL && Count key : int count 2) { count = count + 1; } pres = pres->next; } cout key « endl; 11 Error 2.
The regular queue is a FIFO structure, meaning that you can only enqueue at the rear and dequeue at the front. Suppose that the dequeue operation can also be performed at the rear (so you can remove and return the last element on the queue), which of the following describes the correct and efficient way of using a linked list to implement this queue? OUsing a singly linked list with a reference to the head only, the dequeue method traverses it, stops at the last node and removes it. O Using a singly linked list with a reference to the head only, the dequeue method traverses it, stops at the second to last node and removes the last node. O Using a singly linked list with references that point to the first and the last nodes respectively, the dequeue method removes the last node via the corresponding reference. OUsing a doubly linked list with references that point to the first and the last nodes respectively, the dequeue method can remove the last node via the corresponding reference. O…

Suppose you are tasked with implementing a reverse queue in which elements are enqueued at the front and dequeued at the rear The umplementation is dynamic, and your queue class has Node pointers called front and rear, which point to the front and rear nodes in the queue respectively. The Node struct is given below: struct Node char element; Node * next ; }; Implement the dequeue function of the reverse queue which should return the dequeued value. The function prototype is T dequeue () For the toolbar (PCLor ALT+FN+F10 (Mac).
If the following is a circular array based queue of size 99 43 54 76 93 77 18 If rear is at index 1 and front is at index 6, what is the size of the queue? Answer:
Computer Science CODE IN C++: You have to design and implement a game in which the avatar has to find the hidden treasure in circus. Theonly way to guide the avatar and to find the treasure is to find the shortest path that leads to the hiddentreasure. You, being a developer are bound to use the Queue data structure. Among, depth first search andbreath first search, determine the most suitable algorithm and provide a complete code. Decide the suitablename of the avatar and the game since you are the designer. Data should be taken from the user. Makerelevant assumptions if required
If front=2 and rear=5, how many elements are there in an array-based queue (note: rear is pointing at the next free location) O 3 4 2 5
Node* temp=new node(); if(temp==0) return 0; return 1; we can use this to check if the linked queue is full or not Select one: True False
