Chapter 20, Problem 1FTE
Explanation of Solution
Purpose of the given code:
The given code is used to display the second element in a list “myList”. This list contains three elements.
Given code:
/* Set a reference "ref" to the first node in the list "myList" */
Node ref = myList; //Line 1
/* Increment the value of "ref" */
ref++;//Line 2
/* Display the element in the "ref" */
System.out.print(ref.value); //Line 3
Error in the given code:
- The error is present in “line 2” of given code. If user needs move on to the next node, then they should set a reference to the successor of the existing node. That is assign “ref” to “ref.next”.
- Therefore, user should replace “ref = ref.next” in the place of “ref++”...

… and containing the values(see image)
Using a loop to reach the end of the list, write a code segment that deletes all the nodes in the list. Ensure the code performs all memory ‘cleanup’ functions.
None
Multiple choice in data structures
void doo(node<int>*root){
if(root !=0) { node<int>*p=root;
while(root->next!=0) root=root->next;
p->data=root->data;
}
What is this code do?
a.
swap the first item with the last item in the linked list
b.
set the first item in the linked list as the last item
c.
doesn't do anything because the root parameter is passed by value
d.
change the root item in the binary tree with the farthest leaf item

- Duplicate Set This function will receive a list of elements with duplicate elements. It should add all of the duplicate elements to a set and return the set containing the duplicate elements. A duplicate element is an element found more than one time in the specified list. The order of the set does not matter.

- struct node{ int a; struct node * nextptr; }; Write two functions. One for inserting new values to a link list that uses the given node structure. void insert(struct node **head, int value); Second function is called to count the number of even numbers in the link list. It returns an integer that represents the number of even numbers. int countEvenNumbers(struct node *head); Write a C program that reads a number of integers from the user and insert those integers into a link list (use insert function). Later pass the head pointer of this link list to a function called countEvenNumbers. This function counts and returns the number of even numbers in the list. The returned value will be printed on the screen. Note 1: Do not modify the function prototypes.
