Q8 Queue implemented using two stacks: Version 2 3 Points As in Question 7, let Si be the main stack used to store data and S2 be an auxiliary stack which can be used to relocate data from $1 temporarily to assist with queue operations. Suppose all elements of the queue are in S1 and the top of stack si corresponds to the rear end of the queue. At the end of each enqueue and dequeue operation, stack s2 should be empty. Develop pseudocodes for enqueue and dequeue in your workbook (without submitting to Gradescope). You can assume that the size of each stack is sufficiently large to store all data. Answer the following questions. 08.1 1 Point What is the time complexity of enqueue ? In the options below, parameter n denotes the total number of elements in the queue. enqueue is O(1) enqueue is O(log n) enqueue is O(n) enqueue is O(n log n) enqueue is O(na) enqueue is O(n) Q8.2 1 Point What is the time complexity of dequeue ? In the options below, parameter n denotes the total number of elements in the queue. Odequeue is 0(1) O dequeue is O(log n) dequeue is O(n) O dequeue is O(n log n) O dequeue is O(n) O dequeue is O(n) Q8.3 1 Point Suppose we start with empty stacks S1 and 52. First we perform n enqueue operations and after that n dequeue operations. What is the overall time complexity? O O(1) O O(log n) O O(n) O O(n log n) O O(na) O O(n) O none of the above
