Remove Linked List Elements. Easy. Given the head of a linked list and an integer val, remove all the nodes of the linked list that has Node.val == val, and return the new head. Example 1: Input: head = [1,2,6,3,4,5,6], val = 6. Output: [1,2,3,4,5] Example 2: Input: head = [], val = 1. Output: [] Example 3: Input: head = [7,7,7,7], val = 7.

For example, the insertion operation adds a new element to the linked list. Here's a list of basic linked list operations that we will cover in this article. Traversal - access each element of the linked list; Insertion - adds a new element to the linked list; Deletion - removes the existing elements; Search - find a node in the linked list
Here, the remove() method to remove an element from the linkedlist. The method takes the index number of the element as its parameter. Example 2 Using listIterator () Method.

Remove Elements from a Linked List by Index. Before we move on to another data structure, let's get a couple of last bits of practice with linked lists. Let's write a removeAt method that removes the element at a given index. The method should be called removeAt(index).
The remove() method removes an item from the list, either by position or by value. If a position is specified then this method returns the removed item. If a value is specified then it returns true if the value was found and false otherwise. If a value is specified and multiple elements in the list have the same value then only the first one is ...
