We will use a simple sorting algorithm, Bubble Sort, to sort the elements of a linked list in ascending order below.Make the head as the current node and create another node index for later use. If head is null, return. Else, run a loop till the last node (i.e. NULL). In each ...
[Algorithm] Reverse a linked list It helps to understands how recursive calls works. function Node(val) {return{ val, next:null}; } function LinkedList() {return{ head:null, tail:null, add(val) {constnode =newNode(val);if(!this.head) {this.head =node;this.tail =node;returnnode;...

Insertion in linked list can be done in three different ways. They are explained as follows −Insertion at BeginningIn this operation, we are adding an element at the beginning of the list.Algorithm 1. START 2. Create a node to store the data 3. Check if the list is empty 4. If ...
*The detection of loops in graphs/linked lists is a classic interview question, a good solution to which is Floyd's Algorithm, also known at the "Tortoise and Hare" approach, and this is to move two pointers over the list at different speeds and see if they ever end up at the same ...
