S and Q are integer stacks and priority queues, respectively. C mod 3 is the priority of an element C joining the priority queue Q. In other words, the elements' priority numbers are either 0 or 1 or 2. What is the output of the following code if A, B, and C are integer variables? However, the queue procedures have been modified to work on a priority queue. 1.A = 102.B = 113.C = A+B4.while (C < 110) do5. if (C mod 3) = 0 then PUSH (S,C)6. else ENQUEUE (Q,C)7. A = B8. B = C9.

Consider the current elements and its indexes in the queue of size 15: {index[00]=102, index[01]=165, index[02]=115, index[03]=384, index[04]=248, index[05]=111}, draw a table (like shown below) the sequence of elements using the operations listed from number 1 to 26 using the queue approach (A) - in shifting the elements one position forward every time an element is deleted. The following are the description of other operations to be used that would result in a QUEUE that contains the elements. IsTopValue – returns the value at the TOP of the queue. IsRearValue – returns the value at the REAR of the queue. IsTopIndex – returns the index of the value at the TOP of the queue. IsRearIndex – returns the index of the value at the REAR of the queue. IsIndexOf – returns the index of the specific value. IsValueOf – returns the value of the specific index.

I'm using two stacks to time enqueuing and dequeuing a queue. How long would it take to enqueue every integer from 1 to n, dequeuing 2 items every time I enqueue 4? I just want an estimate.
IN JAVA This triple-ended queue exercise can be found at https://open.kattis.com/problems/teque. The requirements for this program are compatible with those of the Kattis problem, so a solution should produce correct results when submitted on Kattis. The Triple-Ended QUEue supports four operations: push_back x: inserts the element x at the end of the TEQUE push_front x: inserts the element x at the front of the TEQUE push_middle x: inserts the element x so that the insertion index for x is (k + 1)/2 for a 0-based indexed TEQUE. get i: prints out the ith index element (0-based) of the TEQUE. The TEQUE will be implemented as a linked list. The usual implementation requirements apply along with a screenshot of the results from Kattis. Sample input 10 push_back 1 push_front 2 push_back 3 push_front 4 push_middle 5 push_back 6 get 3 push_middle 7 push_middle 8 get 5 Sample Output 1 1 Subject: Java Programming
7 T OR F In terms of operation efficiency, the constructor for a link-based queue performs in O(N), whereas the constructor for an array-based queue performs in O(1).
