A data pattern analyser is to be built that can detect and count up the number
of occurrences of two and three letter same letter sequences in a sequence
(e.g. (a,a) or (b,b,b)). The analyser should stop if it encounters * in the
sequence and return the number of occurrences found up to that point in the
form of a 2-tuple (#2LetterSequences, #3LetterSequences). A 3 letter
sequence should only count as a 3 letter sequence, not an occurrence of two
2 letter sequences. No letter in the input sequence ever occurs more than 3
times in a row.
So, for example:
Input string
(a,b,a,b,b,a,a,*)
(x,x,x,y,y)
(p,q,p,z,z,*)
(*,a,a)
(x,x,a,d,*, s,s,s,l)
