Consider a small circular linked list. How to detect the presence of cycles in this list effectively? |
| A. | Keep one node as head and traverse another temp node till the end to check if its ‘next points to head |
| B. | Have fast and slow pointers with the fast pointer advancing two nodes at a time and slow pointer advancing by one node at a time |
| C. | Cannot determine, you have to pre-define if the list contains cycles |
| D. | Circular linked list itself represents a cycle. So no new cycles cannot be generated |
| Answer» C. Cannot determine, you have to pre-define if the list contains cycles | |
| 2. |
