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?
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
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.
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.
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.
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
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.
