for an extra byte save, you can replace the newline escape with a literal newline; you can't do that in the editor directly but you can paste code with a newline and it works
Given a string and a char, Add an underline before any instance of the char, case-insensitive; In case the char never appear in the string, append the char at end surrounded by ().
You can assume ASCII input, though the screenshot isn't.
Shortest code in each language wins.
Test cases
Search, S =>...
Given two Elementary functions f and g(in expression) such that f(0)=g(0)=0, output an Elementary function(ditto) h(x)=f(x), x<0; g(x), otherwise.
Your output should handle situation when either f(x) or g(x) is undefined but h(x)` is because it choose the other function.
Test cases
f(x)=-x, g(x)=x =
Is there any reason some answers have the language "Python 3.8 (pre-release)"? What features does this version of python have that other versions lack?
The main point is a person in the future should be able to test a solution, even after you are no longer active on the site and unable to update your solution
I'm doing some really janky stuff to try and get it to work without a backend except I'm probably not going to be able to due to how the syntax highlighting needs changing
Write a piece of code that is compatible with both C and Python compilers/interpreters, which can output its own source code.
Quine is quite easy, but how about this double language version?
Hint:
To make your code can be executed by both language compilers/interpreters, here's an example:
#ifdef...
Write a C program A, whose output is a python program B. And run B will output the source code of the very first C program A.
The two pieces of code mustn't be the same. (It's not a "PolyQuine" but similar to it.)
@Themoonisacheese I think the 3.8 prerelease was put on separately because of walrus, and probably would have been rolled back into default 3 after 3.8's full release
@att SAME
I freeze if it's below 70
And 70's still hit or miss
With two layers of warm tops and my only pair of thick sweatpants on, I'm finally starting to feel mostly comfortable so long as I don't move too much, which sucks because I need to move if I'm going to eat the leftovers I just microwaved
Maybe this would be easier if I started the day with warm food faster but it's so hard to walk all the way to the kitchen and then open the fridge if I'm not already not chilly
...in part because I did manage to stay out of bed the first time long enough to look at the thermostat and realize the heat was literally off, then after napping for like 2 more hours I hoped it would be warmer when I got back up :P
That's how I found out that no, it's not an accident/miscommunication/my sister doing things the other 3 of us disagree with
Because even during the warm months she'd actually just lower the temperature without asking anyone, always at night, so it would be like 67 when I woke up and I'd wonder why I'm freezing until I walked down to the thermostat and realize oh yeah that's why
which is funny because NOBODY has a harder time getting up than she does
I think sleeping cold would be comfy if I could time the heat to kick in like 3 hours before I plan to get up, but the extent to which sleeping cold is comfy is orders of magnitude smaller than the extent to which waking up cold sucks
@att For me, lately mornings have been THE time I get to be productive, before I bike to campus for afternoon classes and then come back around dinner time
If I can configure my themostat with a timer I'll configure it to automatically heat to 18 in the morning. But my current appartment doesnt' have that option
I have a 10 by 10 matrix which has integers mod 3 in it. There are two allowed operations. You can add two rows mod 3 or you can add 1 (mod 3,) to one of the numbers. How can you find the minimum number of operations to make the matrix all zeros?
@mousetail that would be very interesting if true! I mean it could be np hard. To be np complete you need to make it a decision problem, eg can it be done in less than x operations?
If it was a game where you get points for solving it in fewer operations, what would you do?
If I have finite time I'd just add 1 to values at random and if two rows where complementary by chance then I'd add the bigger one to the smaller one. Perhaps you could look one or two moves ahead but the search space explodes very rapidly
I feel like part of my strategy might be, like, evaluating the immediate net cost of any given row addition and somehow shooting to do individual increments that make that more profitable
I was going to say matrix rules don't matter but knowing math something not being a matrix does not always mean the solution isn't some theorem about matrixes
@UnrelatedString She just left for the week but left a lamp on in her room, and I think it's an LED bulb but the lamp itself has one of those pulsing dimmer switches that's built for incandescent bulbs because there's this almost imperceptibly fast flickering that makes me feel like I'm in a horror movie whenever I look down the hallways
CMQ Can this matrix problem be formulated as an ILP? Given an n by n binary matrix, I want to find the smallest number of bits that need to be flipped to reduce the rank of the matrix over the field of integers mod 2. I don't think there is a fast algorithm so I was hoping it could be formated as an ILP problem. But I am not sure if the rank restriction allows that.
@mousetail I have been informed that another possible issue is that I'm not physically active enough to start generating enough body heat to feel warm with my warm clothing
Which would suck because if I'm too cold then I don't have the will to move, but when I'm mostly awake enough it should be mostly doable to do some light weights or something
Also I should have left 5 minutes ago but it's so hard to want to 1. take my current sweaters off then 2. bike in my other sweater which will still feel way too cold until I get hot enough to start sweating
...maybe I should just put my rain shell on as a windbreaker
@noodleperson I tried to write a fizzbuzz program in template qdeql once. The hard part wasn’t detecting what to print, it was converting to decimal to print it — 3 and 5 have integer multiplicative inverses mod 256, but 10 doesn’t
@mousetail Idk when it happens relative to other stages, but I believe the reason for paradoxical undressing is because blood gets pulled in toward your core rather than going to your extremities
