Luciano,

Why not GQG and AGGA also? Can each individual character only be used once?

Dear all,
Some time ago (http://groups.google.com.br/group/
microsoft.public.excel.worksheet.functions/browse_thread/thread/

Bernie Deitrick helped me to solve a problem related to palindromes
and repeats detection on a string of letters. At present, I need
perform some change on that macros in order to detect non-redundant
palindromes and repeats. In this way, for the sequence bellow my
solution it would be:

QGAGAAAAAAAAGGAGQGG

13 Palindromes detected
GAG
AGA
GAAAAAAAAG
AA
AAA
AAAA
AAAAA
AAAAAA
AAAAAAA
AAAAAAAA
AGGA
GG
GQG 1 3

Now the solution it would be:

QGAGAAAAAAAAGGAGQGG

13 Non-redundant Palindromes detected

GAG
GAAAAAAAAG
GG

The big palindromes should be preferred in the occurrences.
Thanks in advance,
Luciano

Dear Bernie,
In this case, the palindromes GQG and AGGA should not be detected
because they are part of the other palindromes previously detected or
bigger than them. Yes, each palindrome should be used once.
Thank you for your attention,
Luciano
