Given supermarket customer sequences. Using the AprioriAll algorithm, find length$-$k sequential patterns.

$<\{1,8\}\{2\}\{3\}\{4\}>$

$<\{1\}\{3\}\{4\}\{3,8\}>$

$<\{1\}\{2\}\{3\}\{4\}>$

$<\{1\}\{3\}\{8\}>$

$<\{4\}\{8\}>$

Answer: $],],],,$

$----$

P$.$S$.$

The answer is set in this format: $<1,2>,<1,2,3>,<1,2,3>,<1,2,4>,<2,3,4>.$ That is$,$ you write the number with a comma $(,)$; NO $<>.$

If the answer contains multiple sequences, arrange the sequences in ascending order based on the length of k$.$

If you believe there is no value or sequence for some blanks, insert $0($ZERO$)$ instead. Please fill in the blanks accordingly.
