@yogesh:for linked list that will not work coz loop doesnt always mean
rear->next will be front
hare and tortoise rule will serve the purpose

loop in a link list doesn't necessarily mean a circular link list(d one u
hav assumed)
eg in this case
1->2->3->4->5->3
there is a loop which in order to detect requires d use of hair & tortoise
rule

I am not sure about these...but i guess this will do the job
In Linked List:
(rear->next==front)
In Array:
after reaching the maximum size or the end of queue ...just add one more
element in queue... and after addition just check
(queue[front]==new_element_added) ... if yes then circular queue
in hair and tortoise this they will meet wen 1st pointer(tortoise) is at the
end of the linked list(in 1st traverse) and 2nd pointer( hair) reaches the
same node 2nd time. That means u traversed the list twice.
Its better that since u hv the head of the linked list, keep on moving till
the end .If
@aditya:can u explain ur array approach ?

in arrays i guess it can be simply analysed checking the last element of
array(which can be obtained by sizeof) & checking how the entries are filled
inn the array...
in linked list hair & tortoise rule...initialize two pointers...one's step
size:1, second's step size two... & run through the linke
use hair and tortoise rule for lists
i don think we can do it for arrays

In both the cases... what would be the condition?
