So let’s see how we can approach to remove loop in linked listīefore moving to the approach section, try to think about how you can detect and remove loop in a linked list. Now I think from the above examples detection and removal of a loop in linked list is clear.
So, the final linked list after removing the loop loop will be 1 – > 0 – > 3 – > 0 – > 1 -> NULL.Now, as we found out that there is a loop in the given linked list, so now we have to remove the loop from the linked list.The last node of the loop points back to the first node of the loop. From the linked list, we can see that there is a loop in the linked list starting at the node with value 0 and containing 4 nodes 0, 3, 0, and 1.According to the problem statement, we need to detect and remove loop in a linked list.Let’s understand how we can detect and remove loop in a linked list with the help of some examples. Removing the loop means that the we need to make the last node of the list point to NULL instead of pointing to some other node in the list. The linked list contains a loop means the last node in the list will not be pointing to the NULL instead, it will be pointing to some other node in the list. Problem Statement Understanding to remove loop in linked list
We have to detect the loop, and if there is a loop, we need to remove it from the linked list. In this problem, we are given a singly linked list, which may contain a loop. A loop is a linked list defined as a condition that when the last node of the linked list doesn’t point to the NULL.let’s now try to understand the detection and removal of a loop in linked list. In this article, we will learn to detect and remove loop in a linked list.
