Problem 551. Have you seen any Spindromes recently?
@Amitava: I think test cases 4 and 6 are incorrect. Could you please verify the same?
@Amitava: please ignore my previous comment. Cheers.
Neighbors are more than adjacents. The first and last elements are considered adjacent. Thus [ABAABA] is not a spindrome as it becomes ...AABAABAA...
However [ABA] is a spindrome even though it also becomes ...AABAABAA...
can u be more clear about test suite 4 & 6?
The definition of spindromes is not really clear. But basically it seems that we must look if there is a repeating pattern, if we found one, then the sequence is not a spindrome. On the other hand, AAAXXXAAA should not be a spindrome imho, since it is a repeating pattern AAAXXXAAAAAAXXXAAAAAAXXXAAAAAAXXXAAA ... so we have to limit the test to half of the list size which means AAAXX | XAAA is apparently a spindrome. However BBBXXXBBBXXX is not a spindrome, since we would have BBBXXX | BBBXXX.
