LDQ: Feedback request for a feature I've just come up with: "generic wrapper types"
So basically
This is for a lang with Rust-like OOP. As in, traits.
So a Generic Wrapper Type, or GWT, would wrap any type (with optional trait requirements ofc), hence the name
However, you'd be able to implement more traits on the GWT, and store additional information inside of it
E.g., let's say I have a Vec class
I could make a GWT that stores a pointer alongside the Vec
Which would simplify things that involve keeping track of a position within the Vec (e.g., implementing a tape, or overwriting part of the Vec gradually)
Here's the important part tho
Any methods I run on the GWT would pass through to the Vec inside if they aren't handled by it
So I could .map() it without having to worry about reimplementing map in the wrapper class, or implement a new trait on Vec and have it automatically available in the GWT
Or for example, making an iterator peekable
You could make a Peekable<T: Iter> wrapper which stored an additional &Option<T::Item> (the peeked item), and just wrapped .next to update it
okay not a single answer I found online actually accomplished anything for me so I figured I'd ask here since this feels like a one line fix - how do I stop VSCode automatically completing imports as import db from "../../../../../../../Documents/projects/websites/main/src/db.js";
like, sure it is technically importing a relative path, so setting the module specifier to relative does nothing and setting a base url in the tsconfig compiler options just makes the imports incorrect
How many xor'ed waves?
In this challenge, you're given a list of overlapping waves. Each wave is a finite list with n truthy values, then n falsy values, then n truthy and so on, where n is the wavelength. The values of a wave may have an offset, so a wave of wavelength 3 could be something like ...
also guys am i going crazy or is imposter supposed to be spelled impostor
well anyways, i am kinda pissed rn cuz i spent a while planning out a desmos answer to that sonar impostor question and its not working. like its not giving errors but its just wrong
obviously somewhere my brute force went wrong but like i cant print out intermediate results like in other langs so idek where went wrong
>>> arr = []
>>> for el in arr:
... print(el)
... else:
... print("hmm")
...
hmm
>>> arr = [1]
>>> for el in arr:
... print(el)
... else:
... print("this makes sense")
...
1
this makes sense
>>> for firstElement in arr:
... print(firstElement)
... break
... else:
... print("wut")

@ATaco no, my idea works differently than Python's. In Python, the else is run if the loop ends without break (or presumably return or raise). My idea was that the else is run iff the loop body is never even run.
The Greatest Common Divisor, or gcd, of two positive integers \$x\$ and \$y\$ is the largest positive integer that divides both \$x\$ and \$y\$.
The Least Common Multiple, or lcm, of two positive integers \$x\$ and \$y\$ is the smallest positive integer that is a multiple of \$x\$ and \$y\$.
