Pertemuan ke - 2 27-02-2018 Linked List: - Single Linked List Simplest linked list.  Define a node structure : struct tnode {   int value;   struct tnode *next; }*head=NULL,*tail=NULL,*curr; head is the pointer for the first element in our linked list. tail is the pointer for the last element in our linked list. Insert Head: struct tnode *node =  (struct tnode*) malloc(sizeof(struct tnode)); //make a new node node->value = x; node->next  = head; head = node; Tail: struct tnode *node =  (struct tnode*) malloc(sizeof(struct tnode)); //make a new node node->value = x; node->next  = NULL; tail->next = node; tail = node; Delete // if x is in head node if ( head->value == x ) {   head = head->next;   free(curr); } // if x is in tail node else if(tail->value == x){   while(curr->next!=tail) curr = curr->next; ...
