After a few trials I've written this code where the border of a link expands:
a {
position: relative;
text-decoration: none;
margin:0;
}
a::after{
content: "";
position: absolute;
//relative to a
bottom:0;
left:0;
width:0%;
transition: 0.3s width ease-out;
}
a:hover::after...
The idea is to have a data structure that holds any number of objects of any type. Objects can be retrieved, or removed permanently, at random. Also, it can be cleared (or emptied).
public class Sack
{
private List<object> objects;
public Sack()
{
obj...
I want to create thumbnails from PDF files – specifically, a thumbnail of the first page. Currently I use pdftocairo on the command line:
$ pdftocairo myfile.pdf -png -singlefile -scale-to-x 400 -scale-to-y -1
but I wanted to see if I could implement this without shelling out to an external to...
I am trying to solve this question: https://www.spoj.com/problems/ACTIV/1
The essence of the problem is this: given a list of school classes with start and end times, find the total number of non-overlapping subsets.
I’ve written up a DP solution that I think is optimal in terms of time complex...
I implemented this simulation for a class, but it seems to be very slow. I'm not sure if that's normal or not.
If anyone could take a look at my code and help me out, I'd really appreciate it.
I think it stems from having so many events ($\approx \mathrm{dim}^2\times n$) created in the followi...-1
I'm exploring different and hopefully more reliable and efficient ways to protect sections of my React app that require authentication. My React app uses React-Router to manage routes.
There's this example here but I felt maybe there's a more efficient way.
How about this approach in App.js?

I wrote a class that extends the dict class to provide indexing like functionality, so I can find which key(s) map to a given value in the dict. It's pretty bare bones and there are a lot of things I haven't fleshed out like docstrings (will add these later when I have a final version), how to ha...
I'm fairly new to Html/CSS and I've put together a navigation bar.
I would appreciate some feedback on what I could do better within the code as I don't know what's best just yet.
const navSlide = () => {
const burger = document.querySelector('.burger');
const nav = document.querySelect...
I recently needed to run some command line applications from Python. Whilst this is fairly simple with subprocess.Popen. I wanted to be able to properly pipe the output.
When running the programs from Python I want three things:
The option to have a low memory footprint.
This is possible wit...
I'm currently solving a problem where I should put all even numbers on first positions in vector, and odd numbers last. So, for an input of
vector=[1, 23, 44, 12, 8, 55]
result should be new=[23, 44, 12, 8, 1, 55] or some variations, order of numbers is irrelevant.
So far I managed to create...
Recently I was studying bitwise operators and bit-manipulation algorithms and I found out an algorithm to add two binary numbers.
Pseudocode is as follows:
function add(A, B):
while B is greater than 0:
U = A XOR B, where XOR = Bitwise XOR of A and B.
V = A AND B, where AND...
Problem
Given a set of formulas (AKA "Rules"), get a list containing every possible answer that does not break any formula.
Formula variables can have a maximum equal to the number of characters. For example "ABC" can have values from 0-3 while "E" 0-1.
Example, given this set of Rules:
{AB...
