Explanation of Solution
Replacing the letter ‘N’ with the letter ‘G” using the concept of linked list:
The given table can be represented by the form of linked list concept is shown below:
To replacing the letter ‘N” with the letter “G”, user need to performs the two step. First remove the letter ‘N” from given linked list and then replace with letter ‘G’.
The alphabetical letter from given linked list ‘B’, ‘J’, ‘K’, ‘N’, ‘P’ and ‘X’. So, the given list starts from address “0x32”. That is the given linked list diagram for given arrangement is
Step 1: Remove the letter ‘N’
To remove the entry N from the above list, pointer field of entry must be replaced by the address of entry ‘P. After the address of entry replacement, the given linked list diagram will be

- How is an array stored in main memory? How is a linked list stored in main memory? What are their comparative advantages and disadvantages? Give examples of data that would be best stored as an array and as a linked list.arrow_forwardDo this using C++ language using structures and singly linked list.arrow_forwardWhat is a pointer and what is a linked listarrow_forward
- Following initial state of a queue is reflecting the implementation of a circular array. The front and back pointers are shown on the queue. 67 32 45 b. enqueue(95) c. dequeue front Show the queue state after each of the following operations with updating front and back pointers as required: a. enqueue(23) d. dequeue e. enqueue(11) f. dequeue g. dequeue h. dequeue 44 backarrow_forwardDouble pointers: Describe how this operation can be done in O(1) time if there are pointers in each node to both the previous and the next node.arrow_forward26. In a pointer-based implementation of an linked list. a. increasing the size of the list can waste storage and time b. less memory is required to store an item than in an array-based implementation c. an item explicitly points to the next item d. items can be accessed directly with equal access timearrow_forward
- Data Structures , Code C++ Suppose that p, q, and r are all pointers to nodes in a linked list with 15 nodes. The pointer p points to the first node, q points to the 8th node, and r points to the last node. Write a few lines of code that will make a new copy of the list. You code should set THREE new pointers called x, y, and z so that: x points to the first node of the copy, y points to the 8th node of the copy, and z points to the last node of the copy.arrow_forwardcPP,C++,c++,cpp Language Linked list. Solve the program using c++ language Linked list.arrow_forwardThere are many differences between array and linked list, one of these differences: a. In a linked list insertion and deletion takes more time b. Array supports random access while linked List supports sequential access c. in linked list, elements are stored in contiguous memory location while in array are stored anywhere in the memory d. None of the abovearrow_forward
- head = (node *)malloc(sizeof(node)); which returns a pointer to a structure of type node that has been type defined earlier. The linked list is then created by the function create. The function requests for the number to be placed in the current node that has been created. If the value assigned to the current node is -999, then null is assigned to the pointer variable next and the list ends. Otherwise, memory space is allocated to the next node using again the malloc function and the next value is placed into it. Not that the function create calls itself recursively and the process will continue until we enter the number -999. The items stored in the linked list are printed using the function print which accept a pointer to the current node as an argument. It is a recursive function and stops when it receives a NULL pointer. Printing algorithm is as follows; 1. Start with the first node. 2. While there are valid nodes left to print a) print the current item and b) advance to next node…arrow_forwardSubject-Object oriented programing Write a program which:• creates a new Array List• adds 5 decimal numbers to it• prints the list to the screen In the same program, replace the element in the ArrayList at index 2 by null. Print the resulting list tothe screen.arrow_forwardData Structurearrow_forward
