In this lesson, we will look at how we can reverse a singly linked list in an iterative way and a recursive way.
Let’s first be clear about what we mean by reversing a linked list. Have a look at the illustration below to get a clear idea.
Let’s discuss the algorithm to reverse the linked list as depicted in the illustration above.
Algorithm
Before jumping to the code, let’s figure out the algorithm.
Iterative Implementation
If we look at the reversal above, the key idea is that we’re reversing the orientation of the arrows. For example, node A is initially pointing ...
