  #include<iostream>
using namespace std;
struct node{
	int data;
	node *next;
};


	
int main()
{
	node *head=NULL,*n1=NULL,*n2=NULL,*n3=NULL,*n4=NULL,*n5=NULL;
	n1=new node;
	n2=new node;
	n3=new node;
	n4=new node;
	n5=new node;
	cout<<"please enter the numbers for the link list"<<endl;
	cin>>n1->data;
	n1->next=n2;
	cin>>n2->data;
	n2->next=n3;
	cin>>n3->data;
	n3->next=n4;
	cin>>n4->data;
	n4->next=n5;
	cin>>n5->data;
	n5->next=NULL;
	head=n1;
	int max=n1->data;
	int min=n1->data;
	for(node *loc=n2;loc!=NULL;loc=loc->next)
		{if(loc->data>max){
		max=loc->data;
		n5->data=max;}
	}

	
	for(node *loc=n2;loc!=NULL;loc=loc->next)
	{if(loc->data<min){
	min=loc->data;
	n1->data=min;}
	}
	
	for(node *loc=head;loc!=NULL;loc=loc->next)
		cout<<loc->data<<endl;
	
	
	
	system("pause");
	return 0;
