 clrscr();
 textcolor(11);
 first=NULL;
 avail=(newnode)malloc(sizeof(struct node));
 avail->next=NULL;
 printf("\n\n\t\tENTER VALUE OF NODE WHICH YOU WANT TO CREATE NODE SPACE>>");
 scanf("%d",&n);
 temp=avail;
 for(i=1;i<n;i++)
 {

 temp->next=(newnode)malloc(sizeof(struct node));
 temp=temp->next;
