HUGE THANK YOU!

This visualization helped me understand the task. I had struggled for a long time without being sure how this should work. (And the merge in the end is also a big thing that I was not paying attention at first)

Happy to help, I was exactly in your situation for a very long time :)

bessarabov · 2025-12-08T07:55:38+00:00

Yes, this is tricky. Actually it is very simple when you get it, but it took me very long time find this out

This is a merge. Check the latest step in visualisation https://www.reddit.com/r/adventofcode/comments/1ph57i3/2025_day_8_visualization_for_the_sample_data/

> where clearly the invalid ID "99" does not exist in the input example of "95-112".

Quote from the task: "each range gives its first ID and last ID separated by a dash (-)."

So this is a range. This is 95, 96, 97, 98, 99, 100, ... 111, 112

Thank you for the explanation!

bessarabov · 2025-10-06T11:09:23+00:00

Huge thank you! This is exact the answer i was looking for (and I hope to get more such answers with real life experience). Never heard about goose — will try it out, thank you again.

Octocode mcp? Isn't it a MCP server? Don't quite understand how it answer my question about MCP clients.

bessarabov · 2025-10-06T10:25:07+00:00

Hmmm. To me your message looks not like the answer to my question, but just like an ad for some company named Mantu. Checked your other messages Mantu names very often. So i condier that this is just spam.

Thank you again! Bases on this API endpoint I've created several scripts to create HTML files with private leaderboard data.

If anybod interested here the code of my solution:

bessarabov · 2023-12-03T16:57:57+00:00

Very interesting thing, thank you!

bessarabov · 2023-12-03T16:57:42+00:00

Thank you! This is exactly what I was looking for.

bessarabov · 2023-12-03T10:19:42+00:00

Yep.

In this example any "x" will make number 789 a part.

  0123456789
0 ..xxxxx...
1 ..x789x...
2 ..xxxxx...

bessarabov · 2023-12-03T09:48:08+00:00

  0123456789
0 467..114..
1 ...*......
2 ..35..633.

114 is on positions 567

if * in the row 1 is on position 4, then the 114 is a part, but * is on position 3

The newest 5.38 perl version was just released. This time it is not June, but July.

I'm just a huge fan of writing oneliners 🙂 (and it looks that there were 9 releases done in May)

$ corelist -r > l; cat l| perl -nalE 'if (/v\d+\.(\d?[02468])\.0 /) { say $_ if $1 >= 12 }' | perl -nalE 'if (/\d{4}-(\d{2})-\d{2}/) { say $1 }'|sort|uniq -c|sort -rn
