Got about 400ish instructions down. Decided to approach a few codegolf problems from this unimplemented experimental state. I dont think i intended to make such a tiny grid of asterisks.
10x10 grid of asterisks: I_Unsigned8bitC010 10100 I_Repeat2DSquareC 01010000
Equiv space: 4 1/8 bytes.
Also, semantics question: Is code allowed to take up only part of a byte, or do you have to round up
https://codegolf.stackexchange.com/questions/171943/sum-textsquare2 can be done with
I_Divisors I_Square I_Sum I_IsPerfectSquare 0
Equiv space: 5 1/8 bytes. almost ties with 05AB1E, but the fact I_IsPerfectSquare is dual purpose (Can be a check or a filter) and the fact it takes an extra bit makes it *slightly* larger. RIP.
Write a program that takes a list of strings as input and creates trees of prefixes as such:
Hi_there_how_are_you?
Hi_there_would_you_mind?
Hi_the_weather_is_nice
Hills_are_green
Many_of_us
May_has_11_days

Put +, -, * into 1 _ 2 _ 3 ... n to make the expression equal 0, for a given 3 <= n <= 30, and output the valid equation (0=1+2-3). Exactly one operator between each number.
There exists some patterns, such as ((1-2)-(3-4))+((5-6)-(7-8))... and 1+((2-3)-(4-5))+(6-7). Maybe we can find patterns...
Introduction
Today we're gonna take care of the bane of first-year linear algebra students: matrix definiteness! Apparently this doesn't yet have a challenge so here we go:
Input
A \$n\times n\$ symmetric Matrix \$A\$ in any convenient format (you may also of course only take the upper or the...
Challenge
Your task is to encode an integer as a string of ASCII characters, then successfully decode it after said string has been randomly shuffled.
You will write two programs/functions, which will be referred to as Encoder and Decoder.

Input: an integer \$n\$ in the range \$[0,2^...
Is there a meta post along the lines of "it is sufficient for code golf answers to provably work they don't actually have to yield the correct result on real hardware if eg numerical or runtime issues are a concern"?
Seriously - new tab won't work, whenever I type something into the search bar and hit enter it does nothing... what is happening?
This is outrageous - apparently I had to just close all of my old tabs and windows and completely restart chrome. And after that, if I go to History dropdown and click my tabs again, it freezes and crashes again! So guess I'll have to open 20+ tabs manually...
TFW you intend to solve a challenge all day long but you first try to finish your seemingly endless maths homework, but then you're not in the mood to solve the challenge anymore :(
I've been given no more, no less than 21 exercises, 8 of which were hard af (they were all referenced in the bibliography from national or regional olympiads D:)
We have a logging utility, and someone was upgrading it to support unicode. Except they did this by storing strings as arrays of unicode code points, and then forgot about it, and now we have a bunch of UTF-32 logs.
'cause no one's actually checked the logs in forever
Equalize the array
code-golfarray-manipulation
Challenge
You are given an array \$a\$ of integers. With a move you can increase or decrease an element of the array by 1. Your task is to equalize the array, that is make all the elements of the array equal by performing some moves. But that's no...
Tomorrow is the Mid-Autumn festival, and in the spirit of that holiday, I will introduce a gambling game that we(people from Xiamen) play during the holiday!
Rules
The game is played with six 6-sided dice. Different combinations of numbers have different ranks, with a special emphasis on fours...
