Reverse
Explore how to reverse a singly linked list using both iterative and recursive techniques. Understand the detailed algorithm and pointer adjustments crucial for reversing linked list nodes effectively.
We'll cover the following...
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 to node B but after we flip them, node B points to node A. The same is the case for other nodes. We can take this key observation to solve our problem and ...
