fubarx comments on The "I love you" knock has me choking inside

They have 13 phrases. Could have kept to combination of 3 digits of dots and dashes and still have one slot left over.

If it isn't obvious, I don't have daughters.

Obviously we need to teach them Huffman encoding

They could also just use Knock Code which is a simple way to encode letters as knocks to send arbitrary messages. Most often used by prisoners since it's easy to learn.

Last knock kant be detected to be long or short (right?) so you have to redo it.

You can just add a short knock to the end of every sequence, that should remove any ambiguity

How do you know it’s a short knock at the end and not just a super long knock

But is that the most efficient 🧐? (Probably)

3 and 7 are the same sequence. 8 and 11 are a sequence of 4

EDIT: I looked closer and realized these could be explained by simple typos; 3 would be .., 7 is not a typo, 8 would be ..-, and 11 would be -..
