For todays #FollowFriday I'm going to do something a bit different. We have a lot of new users, one of the biggest surges we have seen in a while. As such a lot of new users are looking for high quality, long-standing, accounts to follow. Similarly many of the new users need some help getting attention and making new friends.

As such I am going to do this #FF in a few parts. One for old users I have mentioned in previous posts, as well as some of the new users who have been making quality posts and been active for at least a week now. Hopefully this will be more helpful.

Also a section for some bots might be useful.

I will use a persons profile description here as I dont want to misrepresent anyone.

This was a really fun programming challenge originally proposed by @Absinthe I want to paste it here, along with my solution, so everyone who is interested can check it out.

Here is the link to his original post: https://qoto.org/@Absinthe/102895801091007015

Another Freebie...

This problem was asked by Facebook.

Given the mapping a = 1, b = 2, ... z = 26, and an encoded message, count the number of ways it can be decoded.

For example, the message '111' would give 3, since it could be decoded as 'aaa', 'ka', and 'ak'.

You can assume that the messages are decodable. For example, '001' is not allowed.

Here is the link to my solution: https://qoto.org/@freemo/102898629821739556

My solution. This should be a somewhat space-optimized solution in ruby based off the modified concept of a Trie.

https://git.qoto.org/snippets/4

If i made this into a Radix Trie by compressing nodes with single children down I could reduce this further.

But since it does work I thought I'd share it as is. I'll update everyone if i decide to finish optimizing this particular solution.

It does however do a fairly decent job at compressing the tree by making sure no subtree is a duplicate of any other part of the tree (a node of any specific length/id will be the only node with that length.

For clarity I attached a picture from my notes of what the Trie would look like for the encoded string "12345" where the value inside each circle/node is the "length" value of that node, and the value attached to an arrow/vector/edge is the "chunk" associated with that link. The end result is any path from the minimum node (0) to the maximum node (5). This diagram does not include incomplete paths which my program does right now.

Incomplete paths can also be trimmed to further reduce the space. But since incomplete paths each add only a single leaf node to the tree, and might be useful for various use cases I decided to keep it.

I also need to improve the display function as it does breadth first not depth first thus breaks the optimization right now.
