Never been to the dwarf planet makemake yet?
Assume a new unexplored planet has several moons spinning around it,
all on a flat circular orbit and equally spaced,
and represented by a sequence of letters such as 'm a k e m a k e'
or simply 'makemake'.
Another example of a sequence of spinning moons could be '0 3 4 6 4 9'
or simply '034649'.
Notice that some moons may have same names.
Assuming that such a sequence could also be called a spindrome if the spinning moons of same names can be distinguishable from each other by the neighbors.
Otherwise that sequence is not a spindrome.
The sequence 'makemake' is not a spindrome.
The sequence '034649' is a spindrome.
Please detect if the given sequence is a spindrome.

@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?

Rafael S.T. Vieira on 16 Oct 2020

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.
