Re^4: Unpack Fail to Decompress String?

With a trailing full length, the last comes first and the first last, with those in the middle keeping their correct relative ordering

So, don't use the actual length, use length mod 4.

input	packed
ACGT	1b 00
ACGTA	1b 01
ACGTAA	1b 02
ACGTAAA	1b 03
ACGTAAAA	1b 00 00
ACGTAAAAA	1b 00 01

Your example in string (byte) sorted order: `input packed ACGT 1b 00 ACGTAAAA 1b 00 00 ACGTAAAAA 1b 00 01 ACGTA 1b 01 ACGTAA 1b 02 ACGTAAA 1b 03` [download] Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
