**Memory Allocation Exercise****Problem Statement:**If P3 is allocated, what is the Base Address (BA)?---**Solution:**Fill in the updated free list as follows:1. **BA:** [blank] ; **Sz:** [blank] → **BA:** [blank] ; **Sz:** [blank]2. [blank] → **BA:** [blank] ; **Sz:** [blank] → **BA:** [blank]---**Explanation:**In this exercise, you need to fill in the Base Address (BA) and Size (Sz) for each memory block in the updated free list after the allocation of P3. The arrows indicate the linkage or sequence of free memory blocks.Consider how memory is allocated and updated, and provide the corresponding BA and Sz values based on the allocation scenario provided. # Memory Management with Dynamic, Variable-Sized PartitioningConsider a memory of size 8KB (8192 bytes) that allows **dynamic, variable-sized** partitioning among processes and uses a linked list to keep track of free spaces (hereafter referred to as the *free list*) in the memory at any given time. Assume that there are 6 processes and each has specific memory size requirements (in bytes) as shown below:- **P1:** 500- **P2:** 600- **P3:** 1300- **P4:** 2000- **P5:** 100- **P6:** 200## Initial State of the Free ListAssume that the initial state of the free list is as follows. Here, *BA* is the base address and *Sz* is the size of each free space:- **BA: 0; Sz: 1100**- **BA: 1200; Sz: 600**- **BA: 2000; Sz: 1800**- **BA: 6000; Sz: 400**This setup allows efficient allocation and deallocation of memory for processes with varying demands, optimizing the use of available resources.

We will use fcfs technique to solve the above problem Given: p1 = 500 p2 = 600 p3 = 1300 p4 = 2000…

The program requires me to remove all item for a list, but when doing the test case for it, it only removes one. What would be the problem in this code?Given code: #include "MovieList.h"#include <iostream> using namespace std;// Constructor functionMovieList::MovieList() { top = nullptr; } // Destructor functionMovieList::~MovieList() { MovieNode *p = nullptr; while (top->next != nullptr) { p = top; top = top->next; delete p; } delete top; p = nullptr; top = nullptr; } void MovieList::display(ostream &out) { MovieNode *t = top; int pos = 0; // Function to display the movie list while (t != nullptr) { out << pos << ": " << t->title << endl; pos++; t = t->next; } } int MovieList::count() { MovieNode *t = top; int pos = 0; // Counting based off the movie list while (t != nullptr) { pos++; t = t->next; } return pos; } void…

With Head node or not? statement is: if(first->llink == first) output << "List is empty"; O a. It is a Doubly linked list without Head node. O b. It is a Doubly linked list with Head node.
'Split List' in Scheme:
In c++, how do I display the last node in a linked list?
struct insert_at_back_of_sll { // Function takes a constant Book as a parameter, inserts that book at the // back of a singly linked list, and returns nothing. void operator()(const Book& book) { /// TO-DO (3) /// // Write the lines of code to insert "book" at the back of "my_sll". Since // the SLL has no size() function and no tail pointer, you must walk the // list looking for the last node. // // HINT: Do not attempt to insert after "my_sll.end()". // ///// END-T0-DO (3) ||||// } std::forward_list& my_sll; };
Every time you write a non-const member function for a linked list, you should always think about if that function is preserving your class invariants. Group of answer choices A. True B. False
Suppose a node of a doubly linked list is defined as follows: struct Node{ int data; struct Node* next; struct Node* prev; }; Write the function definition of the function deleteElement as presented below. This function deletes a node at position n from a doubly linked list. struct Node* deleteElement(struct Node* head, int n){ //write the function definition }
Use the following node definition for this problem.struct NodeInt32{int32_t value; NodeInt32* next;} Write a function which searches a non-empty linked list for a target value. Its exact signature should be: NodeInt32* find(NodeInt32* head, int32_t target); The function should return the first node whose value equals target. If the target is not found in the list, then the function should return NULL.
