So motivated to see you after a very long time!

[argasaragih]

Happy to see you back, Errichto! Your videos are really helpful. Please post more educational videos!

I took me like 6 hours to do it (First time using C++) but I learned a lot and it's nice to see my solution was this close to yours :D

I didn't know you can fill 2 vectors like that in one line tho 2:07 Thanks for the video!

[ShamimKeshani]

I’m glad you’re back; I missed your coding!

[johndoe]

nice to see you. we need more content :)

[dkdm]

Very nice :)
I did it in standard C and it's so much nicer to be able to just use a map in C++.
By the way, 'distance' is also a term for the absolute value of the difference. 🙂👍

Will you compete for the leaderboard, or it's not appropriate at your time?

when i'm at 100% focus on day 1 AOC trying to understand the problem, i'm in fact using this guy's brain.

If map is slow as you said for the part 2 then what else can be used there if the list data was big?

[verified_tinker]

I also thought they were talking about the distance between indices and was very confused.

[shekhar]

Why leftsum-rightsum will not give the correct ans ?
As the logic is add the left one and subtract the right one ?

[nnene]

the webcam is covering part of the code

[zzgallo]

lmfao it took me almost 2 days and over 2k lines of code after pasting the two list in separate vectors 💀
