Description It's
well known that DNA Sequence is a sequence only contains A, C, T and G,
and it's very useful to analyze a segment of DNA Sequence£¬For example,
if a animal's DNA sequence contains segment ATC then it may mean that
the animal may have a genetic disease. Until now scientists have found
several those segments, the problem is how many kinds of DNA sequences
of a species don't contain those segments.
Suppose that DNA sequences of a species is a sequence that consist
of A, C, T and G£¬and the length of sequences is a given integer n.
Input First
line contains two integer m (0 <= m <= 10), n (1 <= n
<=2000000000). Here, m is the number of genetic disease segment, and
n is the length of sequences.
Next m lines each line contain a DNA genetic disease segment, and length of these segments is not larger than 10.
Output An integer, the number of DNA sequences, mod 100000.
