Steps
Concepts
Step 1: Start at the head of the singly linked list.
Step 2: Check if the current node is null. If it is, the list is empty, and there is no last element.
Step 3: While the current node's next pointer is not null, move to the next node in the list.
Step 4: When you reach a node where the next pointer is null, that node is the last element of the list.
