- Need help in Stack/Queue Which of the following statements are correct about the time complexity of the operations of Queue implementations? If not, why? (ex. if 1 is incorrect, write fixed version, like dynamic array is used for implementation) If a circular array is used for implementation, the dequeue operation has a time complexity of O(n). If an array is used for the implementation with the first element in the queue always stored in index 0 of the array, the time complexity of the dequeue operation is O(n). If an array is used for the implementation with the first element in the queue always stored in index 0 of the array, the worst-case time complexity of the enqueue operation is O(n).A drop-out stack is a data structure that acts just like a stack except that if the stack size is n, and the n + 1 element is pushed, the first element is lost. Using an array, create a drop-out stack. (Hint: A circular array implementation would be appropriate.)It is possible to demonstrate the return address of a function by using a series of instructions. Keep in mind that any modifications to the stack must not prohibit the process from returning control to the person who called it.
- In Go Lang 4. Program stack. For the following code, answer the following questions. Assume we are putting everything for our function calls on the stack. · Show what a stack frame/activation record for main() looks like · Show what the stack frame/activation record for the 2nd call to ctTarg look like? (Yes, this means you can skip the other stack frames) · We note that targ does not change value in any recursive call. Why doesn't the compiler just store targ once in one block of memory big enough to store a string? int ctTarg(string* list, int len, string targ) { if (len <= 0) return 0; if (*list == targ) return 1 + ctTarg(list + 1, len - 1, targ); return ctTarg(list + 1, len - 1, targ); } int main() { string pets[] = {"cat", "dog", "mouse", "cat"}; cout << ctTarg(pets, 4, "cat") << endl; }Please explain the distinction between the restricted version of the stack and the unlimited version of the stack.A data structure known as a drop-out stack functions exactly like a stack, with the exception that if the stack size is n, the first element is lost when the n + 1 element is pushed. Apply an array to a drop-out stack. (Hint: It would make sense to implement a circular array.)
- ANSWER ASAP. C++ LANGUAGE ONLY. (NOT C, NOT JAVA, NOT C#) CPP ONLY Using the double-ended linked list C language syntax code below, convert it into C++ and use it as the base. Modify the provided program into the ff: create a new class named student_queue. and then.. Implement the following methods for the class: front() - returns the pointer to the front element of the queue back() - returns the pointer to the back element of the queue push() - allocates memory for a new node and connects it to the existing queue pop() - retrieves the oldest node in the queue, copies the data to a structure, and frees up the memory from the queue empty() - returns 1 or 0 depending on whether the queue is empty or not size() - returns the number of elements in the queue Program code: #include <stdio.h>#include <stdlib.h>typedef struct se_list_type {int num;struct se_list_type* prev;struct se_list_type* next;} se_list;int main() {// Start the listse_list* head = NULL;se_list* cur =…Determine the stack's performance when free.Examine the performance of the stack under situations in which it is allowed to act naturally.
- Describe how we might effectively design a Queue as a "stack pair," which is a pair of Stacks. (Hint: Imagine one stack as the front of the line and the other as the back of the line.A data structure known as a drop-out stack functions exactly like a stack, with the exception that if the stack size is n, the first element is lost when the n + 1 element is pushed. Use an array to implement a drop-out stack. (Hint: It would make sense to implement a circular array.)Explain thoroughly the answers to the following questions: When is it appropriate to implement stack or queue using singly linked list, and when is it appropriate to implement them using doubly linked list? A queue can be implemented using stack. Explain how.
