I've run this code many times on Jupiter Notebook and the outputs seem pretty ok. Why does online judge still say there's no-output?

The following is a quick attempt at testing some limits of my computer:

def main():
numbers = tuple(multiprocessing.Value('Q', 0, lock=False) for _ in range(multiprocessing.cpu_count()))
processes = tuple(multiprocessing.Process(target=count, args=(num...
Can someone please review the below code? I've been trying to make it simpler as one of the reviewer questioned on the code being a bit difficult to read with nullish coalescing and conditional statements clubbed into one.

I'm trying to build a board game and solve it using algorithms such as Monte Carlo Tree Search in C++. My current design follows this python project, in which I have a class hierarchy for Board and a State template as follows
// board.hpp
#ifndef GAME_BOARD_H_
#define GAME_BOARD_H_
#include <vector
I'm new to .NET and find it hard to connect all pieces from Youtube tutorials. The code below works, but I assume it can be (greatly?) improved?
Basically I want to display a product category and the products within. I guess loading the data could be improved? And I can't figure out how to implem...

Here is a SPOJ problem I've been trying to solve:
https://www.spoj.com/problems/PALIN/
My approach is the following:
if the given number is a palindrome I add 1 to it to start looking for the next one.
if the number is NOT a palindrome:
I divide the number into 3 parts:
odd: 12507 --> first = 1...

Lately, I found OpenSSL to be difficult to learn as a beginner, while it can be implemented inside beginner-friendly projects like socket programming. After two weeks of research, I've written the following program. I thought to share it with the community to detect issues that can be ...
I have written a very simple wrapper around std::shared_ptr that supports lazy initialization. Do you see any problems?

public:
LazySharedPtr(Args ... args) :

This is my first question here and I'd like to get some feedback. The program works but I'm not sure the classes I've used are right.
First, a class to calculate the Body Mass Index from a double (kgs) and an integer (height in cm):

I know how to solve this issue with simple switch statements. However, I would like to solve it using arrays and if/else statements. I seem to only get 0 hold for all of my inputs.
var count = 0;
var arr = [[2,3,4,5,6],[7,8,9],[10,'J','Q','K','A']]

I am learning Swift and just had a quick question about use of parentheses. The code below runs just fine w/o using parentheses, but it certainly looks a lot cleaner using them in this instance.
So my question is: In SwiftUI, is it basic practice to use parentheses for the sake of cleanliness? Mi...

This is a follow-up question for ConvertAll Methods Implementation for Multidimensional Array in C#. Thanks to aepot's answer and Olivier's answer. In order to match the usage of the build-in API Array.ConvertAll, the input /output array types of the implemented methods below are similar to [], [...
I am trying to perform a certain numerical computation in Python with Numpy:
