Can you tell me how to check whether a linked list is circular?

Create two pointers, and set both to the start of the list. Update each
as follows:
while (pointer1) {
pointer1 = pointer1->next;
pointer2 = pointer2->next;
if (pointer2) pointer2=pointer2->next;
if (pointer1 == pointer2) {
print ("circular");
}}
If a list is circular, at some point pointer2 will wrap around and be
either at the item just before pointer1, or the item before that. Either
way, its either 1 or 2 jumps until they meet.
