Deleting an element from a doubly linked list
WebNov 30, 2024 · Consider a singly linked list first. If you want to delete element f, then you need to update the pointer of element e (that previously pointed to f) to point to g. Since you don't know who e is, you have to find it by using an exhaustive search from the beginning of the list. This requires time Θ ( n) in the worst case. WebMay 21, 2024 · The item variable will store the actual element of the node. The next stores the address to the next node, while prev stores the address to the previous node in the doubly linked list. In the next step, we will create a doublyLinkedList class, that contains different functions to insert, delete and display elements of doubly linked list.

Web1. Your simplified checks should work, but I think they are a bit harder to understand (and technically, it's still four cases). I also wouldn't split the method, but if you do, I would do it like this: Change your void remove (T) method to Node search (T), then add a new remove (T) method which uses search and remove.
