I was surprised seeing ton of people going for the replace approach. It didn’t even cross my mind to edit the string, I went straight for regex for part 1 and it was easy enough to adapt it for part 2.
On the surface level it makes sense since you already wrote the code to extract the numbers based on digits, which will be in the back of your mind. Once you have some time think about though, it’s obvious it’s better to just directly find the first and last “digit” without changing the string.
I did this exact thing and hit the point where it didn’t work. I appreciated that the problem broke my code because it made me arrive at a better solution.
My solution was worse than most: replace one -> one1one You are only going to do the replace all for each number and if the “e” is also in eight it is still there for the next set of replace.
A better quick and dirty solution from Mastodon was to just add the common character first: twone -> twoone
I just check every substring haha
The problem is that 21 is not the only problematic combination.
You can also use o1e as there are never more than a single shared character. It also doesn’t change the string size so it can be done in place. Still an ugly hack of a solution.
I have hacked together the ugliest of solutions and got my two stars but at what price?
I just reverse the string and reverse the number names >_>
Cheater?
Maybe…
That’s clever. Way more than my Regex abomination
everything
Just saw this community and it looks cool even though I’m probably not capable of solving most of the puzzles. But having looked through the community, I can only really find solution threads. Where are the actual puzzles posted so I can give it a go?
https://adventofcode.com/2023 The first question is public, login to get your test data and submit your answers and unlock part 2.
But I don’t wanna log in, though. I don’t care about the leaderboards or anything like that, and call me old fashioned, but I don’t like giving my identity to every little website I visit as a matter of general principles.
There is an anon mode, but it does want you to log in to keep track of progress, either through Google, GitHub etc. I do wish there was a true logless mode but I think it’s cool enough for me to just want to do
Like they don’t track you just by visiting? Also, no one said you need to “give them your identity”. Make up one.
What, you didn’t give them your social security number, passport, dental records, and three generations of birth certificates?
genuinely dont understand why people spend their christmas doing extra unpaid work
unpaid work
This is like whining that a journalist doing a crossword puzzle is “unpaid work” because they use words at their day job.
None of these puzzles are remotely like actual work. It’s for fun. Can’t you just have fun for a couple hours?
I think I just don’t understand how people can have their hobby be related to their work without imploding. I had a cousin who became a proffessional chef and he cooked for fun. That job almost overwhelmed him because he had no escape from its stresses.
I would worry about that happening to me with coding
I’m curious how many programmers encounter these sort of silly challenges during work.
It’s as much work as crosswords are for linguists from my point of view. It’s just a fun brain teaser, and a good excuse to try out new languages.
