Questions & Step-by-Step Solutions

In a circular linked list, what is the main characteristic?
  • Step 1: Understand what a linked list is. A linked list is a data structure where each element (node) points to the next one.
  • Step 2: In a regular linked list, the last node points to 'null' or nothing, indicating the end of the list.
  • Step 3: In a circular linked list, the last node does not point to 'null'. Instead, it points back to the first node.
  • Step 4: This creates a circular structure, where you can keep going around the list without hitting an end.
