Explanation of Solution

Linked list:

Linked list is a linear and dynamic data structure which is used to organize data; it contains sequence of elements which are connected together in memory to form a chain. The every element of linked list is called as a node.

List head:

List head is a pointer used to point the first node in the linked list and it is also called as “head pointer”; if the “head pointer” points to a “NULL” value, then it is considered that the “list is empty”.

Graphical representation of linked list:

The graphical representation of a linked list is as follows:

Function to print the value stored in the first node of a list:

//Definition of printing the first node function

void printFirst(ListNode *ptr)

{

/*Check the list w...

Computer Science In c++ (There should be three different files, "main.cpp", "sourcefile.cpp" and "header.cpp" your solution must have those three different files): Write a function that checks if the nodes in a linked list is sorted in ascending order. The function should return true if the values are sorted, otherwise false. Take user input. Call the funciton in the main function to show it is working.
JAVA CODE PLEASE Linked List Practice ll by CodeChum Admin Write a function printNodes that takes in the head of a linked list and prints all the values of that linked list using a while loop. Print the values separated by a [space]->[space] In the main function, write a program that asks the user to input five integers and assign these values to the nodes. Arrange the nodes in ascending order first before printing them using the printNodes function. Input 1. One line containing an integer 2. One line containing an integer 3. One line containing an integer 4. One line containing an integer 5. One line containing an integer Output Enter·number·1:·1 Enter·number·2:·2 Enter·number·3:·3 Enter·number·4:·4 Enter·number·5:·5 1·->·2·->·3·->·4·->·5
Write the following function that sorts and merges two lists into a new sorted list. The new list contains only even numbers.   def myMergeEvenList(list1, list2):   Enter list1: 10,5,6,7 Enter list2: 12,8,5,0,1 The merged list is: 0,6,8,10,12
