I guess this really just boils down to a question of inheritance vs composition. I've typically heard people advocate for composition more, but I am wondering if that holds true in an example like this. The example is a basic type that will accept DOM events including a custom "poke" event. Setup...

The following code represents a simple indexed binary search tree of integers. The insert method inserts an int. The indexed lookup looks up the ith smallest element (0 indexed). I'm trying to write C++ that is idiomatic, clean, modern, and efficient in that order. Can people give me pointers? #i...

I have written some code that shows a div class, based on what ID is clicked. I'm a beginner, so not sure how to make this code compact, it seems way too long at the moment. Can anyone suggest a better way to write it please? Thank you in advance. $("#Thumb1").on("click", function() { $('.v1')....

I would appreciate review of this implementation of the concurrent list that is, to my knowledge, currently missing in .NET Core. Requirements Thread safe Lock free Ordered Supports get and set by index Implements generic IList Acceptable performance and time complexity compared to regular IList...

Problem Inputs: 1. min length of subsequence 2. binary sequence outputs: 1. starting index of sequence 2. subsequence length The task is to find a subsequence from the given binary sequence with highest win rate. The subsequence should be at least of given min length. 1 = win, 0 = loss win rate...

I'm working on the following task from Codility: A prime is a positive integer X that has exactly two distinct divisors: 1 and X. The first few prime integers are 2, 3, 5, 7, 11 and 13. A prime D is called a prime divisor of a positive integer P if there exists a positive integer K such that D *...

I have a table in my email and on every device and email providers works well, but on newest iOS gmail app the table is transformed. What could I change to improve this table? My code: <link rel="stylesheet" type="text/css" media="screen and (max-device-width: 480px)" href="shetland.css"> <!...

I am trying to find a method to shear/skew an image horizontally or vertically by n degrees (n ranges from -90 to 90 excluding the terminals) so that the result would meet the following conditions: The result would keep the size of the dimension that is not sheared, it means if you shear the ima...

I have a class with a "mode" state. There are currently two modes and we are not likley to add more in the future. The class has a CurrentMode property, and a function to swap to the other mode. I have implimented this using another property called ModeNotInUse which returns the oposite value of ...

Singletons can be very tricky to work with in Unity, especially when you dont want to give up on Monobehaviour features. Most examples I've seen make use of Awake to initialise, but this requires careful managing of script execution order, here is my attempt at a "lazy instantiated" (kind-of) sin...

There are frozenset in Python, but no frozendict or frozenmap. I tried to implement it (Don't care too much about class naming, because I want to try to imitate the standard library) with frozenset, which is almost perfect: from typing import Any, NamedTuple from collections.abc import Hashable, ...

I have converted my Java answer from this question into Rust. As I am new to Rust, I would like to know about what I could improve in my code. Mostly I would guess that I could improve on borrowing, references and ownership / lifetime. The original question aimed to "group objects into the minimu...

Can someone point out what possible edge cases/leaks/inefficiencies my code has and how they could be avoided/fixed. Basically, I want to know what mistakes I make so I can avoid making them in the future. I chose an LSD radix sort function as a sample for no particular reason. The function: //ar...

I have the following VBA code (across three modules) to make UDFs to calculate sun & moon position data. The issue I'm facing is that they are very slow to run as I have over 6000 rows (over 10 years of sun/moon position data for multiple locations), and a sheet calculation takes ages when openin...

Do you think this could be useful in some use-case? Maybe there's a better way to do this? #include <new> #include <type_traits> template <typename A, std::size_t N = 128> class static_new { A* p_; template <auto> static constinit inline A storage_; static constinit inline std::size_t ...

Any improvements on this combination generator. Seen a lot of combination generators online, but none like this. Found pseudocode at: https://www.baeldung.com/cs/generate-k-combinations Fastest I could make, make it FASTER if you can. Also appreciate improvements in code structure and oop, fairly...

I computed a 2D vector field U = (u(x,y), v(x,y)) with radial symmetry, parametrized as (u,v) = a(r) (x,y) + b(r) (-y,x), where a(r), b(r) are given as solution of an IVP which I solved using Y = scipy.integrate.solve_ivp(..., dense_output=True), which yields a solution function Y.sol: r ↦ array(...

I made a text-based game to learn python, since then I have tried to implement what I have found online to be "good practices", does this follow good practices? Also is there a way to escape the repetition of? requestAndValidateUserInput() if endCombat: return I need the retu...
