Question
In a doubly linked list, what’s the “tail” of a linked list?It’s the node with the pointer to the previous node equal to NULLIt’s the node with the pointer to the next node equal to NULL
Solution 1
The "tail" of a doubly linked list is the node with the pointer to the next node equal to NULL. This is because in a doubly linked list, each node contains a data part and two pointers, one pointing to the next node and one to the previous node. The tail is the last node, so it does not have a next node to point to, hence the pointer to the next node is NULL.
Solution 2
The "tail" of a doubly linked list is the node with the pointer to the next node equal to NULL. This is because in a doubly linked list, each node contains a data part and two pointers, one pointing to the next node and one to the previous node. The tail is the last node, so it doesn't have a next node to point to, hence the pointer to the next node is NULL.
