-🎄- 2022 Day 3 Solutions -🎄-

J from

I have both of the parts as 12 lines in Python 😎

Python

OMG, openAI just provided me:

Efficient and understandable solution to both tasks in Python. If you have some problems with the tasks it can maybe help you. Using intersection and ASCII seems pretty neat imo.

My own language

Javascript

Java

Bit late to the party, but Python. Full brute force.

I did it with full brute force too, but i wanna find different solution without it. Do you have any ideas? I searched whole internet in hopes to find some build in functions which find the even letter in string. I thought i would do that if i sort the string and then remove the unnecessary stuff but it would be more complicated and probably even slower than the brute force

My solutions in Python:

JavaScript Day 3

TensorFlow

Solution in JavaScript:

Rust

TypeScript

In single-statement t-sql

Python - Dont try to understand... (Part 1 and 2 in 4 lines)

Inlined code is intended for short snippets of code only. Your code "block" right now is unreadable on old.reddit and many mobile clients; it's all on one line and gets cut off at the edge of the screen because it is not horizontally scrollable.

Kotlin

JavaScript Part 1 & 2

Here's

JQ

JAVASCRIPT PART 2. Hello, It's me again. I'm learning JS, still a beginner. Started my journey back in september this year. You'll see a lot of if statements and console.logs because that's how I manage to keep my line of thought and to check if my code is working. I still don't know how to condensate everything in shorter cleaner code. I'm doing what I can, I think tis activities are pretty fun =)

protip

Err... next time, please don't make 2 posts; combine them into one post.

Keep doing what you started, looks cool! :) My experience is that first we learn consistency and then we can go for efficiency and compactness.

Both of your part 1 and 2 code blocks are too long for the megathreads. Please read our article on

I had the same reaction! Always saw Chunk() but never used it! Feels good to use niche tools

Emacs Lisp:

Go solution based on bitsets with O(1) space requirements.

I'm no go expert, but even looking it up in the

PHP to convert from ASCII character decimal value to the score you want:

You can avoid the ASCII range check by using ctype_upper

thanks for that video, i learned a few tricks there. i can't quite figure out how your code understands to look for input in the text files, however, especially in part 2. wouldn't input() cause a prompt to appear for you to manually enter in input?

C# with one line linq

Thank you for the Chunk function!

Kotlin

Nice, learned some Kotlin things here, thanks!

Yet another Python based snakey one. Also a bit late to the party due to other commitments.

Python 3

Terraform / HCL

Python 3 (covers both part one and two) :

Julia. Learning Sets and map vs comprehension, and now realising some splatting and indexof would have been nice.

Clojure implementation from a beginner in clojure:

Just so you know, (map seq) does the same thing as (map #(map char %)) when you have a sequence of strings

Nim

If I specialize fold to add-up, because there is a lot of adding up in fold/reduces in general:

Common Lisp

C# LinqPad

Hello, I am a noob. I like your solution! I was just wondering, how is it that you get the source text file into Linqpad? Thanks heaps for any tips.

Rust, short and sweet, no_std, no allocations, all bit fiddling:

Very neat even if I don't fully understand how the bit stuff works. Are you basically using the strings as bit masks? Not sure how the u64::BITS - common.leading_zeros() part works either.
