WebThe problem we are exploring is to find the middle element of a singly linked list. For instance, if the linked list is 1 -> 2 -> 3 -> 4 -> 5, then the middle element is 3. If there are even number of elements in a linked list such as 1 -> 2 -> 3 -> 4 -> 5 -> 6, then the middle element is 3 and 4. There are two (2) approaches to solve this problem: WebStep 5– Linked list constructor. Step 6– Add a function to find the size of a linked list. // return this.size. Step 7 – Check whether the linked list is empty or not // return this.size == 0. Step 8– run a loop for traversing the pointer and then print the linked list. Step 9– Add a node in the beginning.
