Insertion at the beginning Insertion in-between nodes Insertion at the End Suppose we have a double-linked list with elements 1, 2, and 3. Original doubly linked list 1. Insertion at the Beginning Let's add a node with value 6 at the beginning of the doubly linked list we made above...

We have only covered three basic linked list operations above: traversal (or search), node deletion, and node insertion. There are a lot of other operations that could be done with linked lists, like sorting for example. Previously in the tutorial we have covered many sorting algorithms, and...
This linked list defines the encounter order (the order of iteration), which is normally the order in which keys were inserted into the map (insertion-order). The least recently inserted entry (the eldest) is first, and the youngest entry is last. Note that encounter order is not affected...
Explanation: In the figure above, there is a sorted circular list of three elements. You are given a reference to the node with value 3, and we need to insert 2 into the list. The new node should be inserted between node 1 and node 3. After the insertion, the list should look like...
get(index) : Get the value of the index-th node in the linked list. If the index is invalid, return -1. addAtHead(val) : Add a node of value val before the first element of the linked list. After the insertion, the new node will be the first node of the linked list. addAtTa...
This linked list defines the iteration ordering, which is the order in which elements were inserted into the set (insertion-order). Note that insertion order is not affected if an element is re-inserted into the set. (An element e is reinserted into a set s if s.add(e) is invoked ...
