Write a program to implement linked list data structure thatwill have following functions:

a. Append a node in the list

b. Insert a node in the list

c. Delete a node from the list

d. Display list

e. Find maximum value in the list

f. Find how many times a value exists in the list.

g. Search

Portion of the code is give below. You have to write code forthe items (e, f, g)

Program:

#include

#include

#include

struct node {

int data;

node* next;

};

node* head=NULL;

void appendNode(int value){

node *newNode, *curr;

newNode = new node();

newNode->data=value;

newNode->next=NULL;

if (!head)

head=newNode;

else // Otherwise, insert newNode at end

{

curr=head;

while (curr->next)

curr = curr->next;

curr->next = newNode; }

}

void insertNode(int value){

node *newNode, *curr, *previous;

}

newNode = new node();

newNode->data = value;

if (head==NULL) { head = newNode;

newNode->next = NULL;

}

else {

curr = head;

while (curr != NULL && curr->data < value)previous = curr;

curr = curr->next;

}

if (previous == NULL)

{head = newNode;

newNode->next = curr;}

else {previous->next = newNode;

newNode->next = curr;}

}

}

// Deleting first node deletedNode = head; head = head->next;

} else{

// Deleting other nodes deletedNode = curr->next;curr->next = deletedNode ->next;

}

}
