Here is a problem that can be modeled using a directed graph with different costs on each edge.
Our input is an array of edges.
const edges = [['A', 'B', 20], ['B', 'C', 10], ['A', 'C', 50], ['B', 'D', 5], ['D', 'C', 2]]
['A', 'B', 20], meaning that from A to B the cost is 20. I wanted to write ...
I'm building a "design system",I'm having trouble getting my menu to work properly. My site is in php and jquery, and I am using ajax to reload the content.
Here is my html layout :

<div class="flex-row">
<div id="menu" class="flex-col-xs-12 flex-col-md-2 g...
I tried to write a program that checks if a file is executable, and if so, to check if it is binary or shell script.
And my question is: is it the best implementation? Or I can write differently?
#include <unistd.h>
#include <stdio.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <string.h>...
I have a cycle which goes from -55 to -1, then from 1 to 55 before going back to -55 again. I want to make a loop going from an arbitrary point in this loop to another arbitrary point, but never as far as a full cycle.
Since the end value of the counter might be either a larger or smaller than th...
This is a question, I'm just not quite sure about:
Every Android development tutorial you find, will put all of the code simply into the MainActivity class (or some other class, that inherits from an Activity class).
But what if you want to put code into your own classes? How do you best access c...

I'm clearly making an obvious binding mistake that somehow I don't see.
If I replace the ng-hide/ng-show with an *ngIf it works, yet

THE PROBLEM:
The coin is tossed four times. What is the probability of getting 2 heads and 2 tails? Determine the solution analytically and then by simulating a given problem, determine an estimate of the required probability for a large number of simulations.
My idea was to make cointoss funct...
When review low quality posts queue, sometimes I stumble on answers which provide alternative solutions instead of reviewing the OP's code.
It would be nice to add this entry (alternative solution) to this list:
I saw quite a few posts about making a dynamic array so I tried to make my own for learning purposes.
Here it is:

#include <stdlib.h>
#include <stdbool.h>
#include <string.h>
#ifndef VECTOR_RESERVE_SIZE
#define VECTOR_RESERVE_SIZE 4

I'm working on Rcpp and I wrote the following code
#include <RcppArmadilloExtensions/sample.h>
using namespace Rcpp;
// [[Rcpp::export]]
arma::mat SIZA(int K){
arma::mat P;
P.ones(K,K);
P = trimatu(P);
for(int idx=1; idx<K; ++idx){
arma::mat W;
arma::mat Hlp;

When writing a MathJax heavy post I noticed a couple of bugs.
For reference, here is an example of how the MathJax should look:
$$
a_{i+1} = \begin{cases}
\frac{a_i}{2} & \text{if $a_i \% 2 = 0$ (even)} \\
3a_i + 1 & \text{if $a_i \% 2 = 1$ (odd)}
\end{cases}
$$

return new Promise((resolve, reject) => {

I'm a long standing PHP, JS, C#(Unity) dev looking to get outside objects and lower down. I've written a quick program to read binary data from a .sav file, and output the data section into CSV's in either long or flat format, with optional leading row indexes.

As part of my Signals library, I needed to create a custom Linked List with the below properties
It should allow "addition" and "removal" of items during iteration, aka when iterator() is called, like in the for loop.
It should ignore-Addition of duplicated items.
It should ignore-Removal of non...
I made a randomized algorithm to solve the three sum problem. There are two key parameters: number of solutions, and total. Notably, the algorithm might generate a duplicate solution. This is not checked since there is no guarantee that there is N unique solutions. The code is below.

This is a lightweight text based version of the popular game Snake written entirely in C. In order to build it, ncurses needs to be installed on the system. Navigation is done using the vim-keys and you can quit with 'q'. The bones of the snake are stored in a linked list. This is one of my perso...
I'm in the process of streamlining my code, which works but it completely unmanageable. My main window has a structure like this:

There are (3) notebooks, each with 3-5 frames. Because my current code has...
I need to have a bunch of hardcoded const objects, something like

I need to be able to access these consts fr...
