A data pattern analyser is to be built that can detect and count up the number of occurrences of strictly increasing and strictly decreasing sequences of three numbers in an input sequence. So for the sequence (1,2,3,4) there are two strictly increasing sequences (1,2,3) and (2,3,4). The analyser should stop if it encounters 0 in the input sequence and return the number of occurrences found up to that point in the form of a 2-tuple (#increasing, #decreasing).

Transcribed Image Text:A data pattern analyser is to be built that can detect and count up the number
of occurrences of strictly increasing and strictly decreasing sequences of
three numbers in an input sequence. So for the sequence (1,2,3,4) there are
two strictly increasing sequences (1,2,3) and (2,3,4).
The analyser should stop if it encounters 0 in the input sequence and return
the number of occurrences found up to that point in the form of a 2-tuple
(#increasing, #decreasing).
