I have created this first-timer implementation of Merge Sort
and I got confused by the C++ Syntax once or twice.
So I have some questions about this code:
#include <iostream>
#include <thread>
#include <cstdlib>
#include <vector>
#define NUM 1048576*2
int sort(std::vector<int>* vec);
void run...
I am new to this community so please pardon if I didn't ask the questions in the proper manner. I am trying to integrate an array of data using scipy.integrate.quad. In Matlab it is easy to do so using
integrate(fun,a,b,'ArrayedValue',true)
In python, I have read on google that similar can b...
It takes in a string from the command line. prints out the length of the string.
I'm mostly looking for tips and general convention suggestions
But I'm open to any other criticism also.
Roast it please thanks.

In a previous meta question, we decided that the sorting tags should not be merged. I am fine with this.
Currently, however, there is a peculiarity among the 6 major sorting algorithm tags:
mergesort — instead of merge-sort
quick-sort
insertion-sort
radix-sort
heap-sort
bucket-sort
you can ...
Recently got this coding assignment as the first round of interview at a tech organization. I could get the expected result, however, my code failed the best practices check.
Please let me know if it needs a different approach or specific things are missing. I was confused about how to add tests ...

I am doing a Pandas project on alcohol consumption. For your information, the dataset has the following columns:
| Continent | Country | Beer | Spirit | Wine |
The following is my code:

I had an interesting chat with a C/C++ programmer regarding the following code:
function example(maybeTrue) {
if(maybeTrue) {
// ...lots of code
return 1;
} else {
// ...lots of code
return 0;
}
}
function example(maybeTrue) {

I crated a CLI tool which executes an npm command (to create a react app) and modifies the contents of the generated files. It was a practice attempt at creating CLI tools for NodeJS and a chance for me to experience publishing NPM packages.
What I set out to do

I have been asked to solve 2 javascript questions and I was thinking I did pretty well because I cover edge cases, wrote almost every possible test case, documented code by jsdoc. Because I don't have someone to give better feedback right now I just wanted to ask in here so I can see what's wrong...
I can't seem to plot the data from this text file because of the format of the data. I can't find anything about plotting numbers with an exponential. Does anyone have a solution? The text file is two columns of data spaced by a tab where the first number is negative and multiplied by some expone...
this is my code to implement DFS with recursion but no stack. I ran few test cases which turned out to be positive but wanted to check the efficiency of the code.
graph = {'A': set(['B', 'C']),
'B': set(['A', 'D', 'E']),
'C': set(['A', 'E']),
'D': set(['B', 'F']),

Just for fun and practice purpose, I have written a short program in C# console with few classes which will create 30 seats for a cinema during program initialization with these options.
Print all seats
Seed 20 random taken seats
Print all empty seats

Imagine a decent scenario where I have on object I want to edit.
Example of an object:
{
id:1,
title:'asda',
labels:[]
//and at least 10 more properties
}
Question:
Is it worth passing each object properties as props (when having 10+ properties)?
How would one deal with lists (object prop...
I just implemented a version of A* search in JavaScript for educational purposes. I'd really love it if you could take a look and tell me how to improve my code.
The grid passed in is just a multidimensional array (2-D array) where each slot in the inner array is an object with property weight.

I have two lists:
Users - [<UserObject1>, <UserObject2>, ...]
Contributions - [<ContributionObject1>, <ContributionObject2>, ...]
Every ContributionObject further can have single or multiple UserObject in it which are mentioned as person_links here and both the objects that are ContributionOb...
I have some legacy code which gets a list of Students and their corresponding School. It's LinqToSql and there is no lazy loading:

02/02/2020 is a palindrome day because reading the date left-to-right or right-to-left still refers to the same calendar date. And because it doesn't
matter whether you use the DD/MM/YYYY format or the MM.DD.YYYY format, it's called a Universal Palindrome Day.
No one year can have more than 1...
I'm trying to calculate with SUMIFS and COUNTIFS some data.
The output sheet looks like this:
I've hidden some irrelevant or sensitive data to make it easy to go to the point.
My code runs an array on this worksheet and calculates per each day and user some KPIs I need from this worksheet:

This is not a traditional maze where you find the shortest path (like the gif on the left). In order to solve it, you need to visit every available node before reaching the end, where once a node is visited it turns into a wall (like the gif on the right).

I am looking to optimize one function that returns error messages to the user.

I'd like to randomly select an array element (Number) by its value/weight, where each weight determines each probability.
// e.g.
// Array
[1.5, 3.5, 2, 1.3]
// Probabilities (%):
[18.07, 42.16, 24.09, 15.66]
So I coded a function which gets an array, chooses an index (Randomly but probabil...
