Singly Linked List Insertion

Let's look at the C++ implementation for the insertion of a node in a linked list.

In this lesson, we are going to briefly explain the basic operations which were discussed in the previous lesson. The three types of insertion strategies used in Singly linked-list are:

  1. Insert at Head
  2. Insert at Tail
  3. Insert at the N-th index

Insertion at Head #

This type of insertion means that we want to insert a new element as the first element of the list. As a result, the head pointer will point to the newly​ added node, whose nextElement, in turn, will point to the node previously pointed by the head or null value.
