I need to compare a title for 3 strings
here what I'm doing
var textMessage = ""
props.screen == 'dd' ? textMessage = "Next, select the dd " : null
props.screen == 'ff' ? textMessage = "Next, select the ff " : null
props.screen == 'ss' ? textMessage = "Next, select the ss " : null
It was not obvious how to get a random member of a container. So I wrote a function to retrive it given a generator.

namespace Util

using Distribution = std::uniform_int_distribution<int>;
/* Get a distribution from [0, max) */

I wrote a class that opens a shared memory communication to use in my project, and would like a review.

Many a times, I've had the need to use a permutations with replacement function.
So, I've written a function to do just that:
from sys import setrecursionlimit
setrecursionlimit(10 ** 9)
def permutations_with_replacement(n: int, m: int, cur=None):
if cur is None:
cur = []
if n...

I have given the Mars Rover challenge a go in Python as DSA practice.
Here is the challenge:
A rover’s position and location is represented by a combination of x and y co-ordinates and a letter representing one of the four cardinal compass points. The plateau is divided up into a grid to sim...
I am working on a project that has to load a lot of data from JSON files. For this I have written the following struct.
struct JsonHelper {
static func parseJsonFile(file: String) -> Any? {
if let filepath = Bundle.main.path(forResource: file, ofType: "json") {
if let con...
Anyone please review and share your feedback for the following code.
Multiple consumers generate random integer numbers and a single consumer receives it to display only odd numbers out of it.

"fmt"
"time"
"math/rand"
"sync"
)
var msgs = make(chan int)
var dummy = make(c...
I am trying to check that a list of files are all images using functional programming.
Some actions I go through are asynchronous, so I have to wait for them to completely finish before passing to a new one.

Given a positive integer n, find the smallest number of perfect squares (for example, 1, 4, 9, 16, ...) that sum to n.
sums = {0:0, 1:1}
def numSquares(n: int) -> int:
if n in sums:
return sums[n]
else:
s = 2**31
squares = [i**2 for i in range(1, int(n**(1/2)) + 1...
TLDR: Does the javascript community regard it as poor syntax to include a terminating semi-colon inside an anonymous function inside an Event Listener / Event Assignment statement, when the terminating semi-colon of the statement itself will be following not long after?
I'm currently writing a...
I want to store a value in a dict (to behave like a cache) but I care about performances. I wonder if it is better to create a second variable in order to store the result of the sum compared to retrieving the value from the dict where the result is already stored.
Real code:
@property

I have written a Matrix library that contains all the main properties of matrices.
It's a relatively long project, I am hoping it is ok to post here since I really want to have it reviewed.
The project is compiled in GCC 9.2.0 and Boost 1.71.0, from https://nuwen.net/mingw.html, environment cod...
This code structure allows me to quickly create and manage behaviours on p5.js sketches. I'm planning to move to Java but wanted feedback beforehand.
The behaviour interface:

Coming back to C++ after a hiatus in Java. Attempting to create an immutable object. Defined A in header as

Want to defensive check that A is positive in the constructor. Is this sane?

So I wanted to write a script that would essentially print out the longest repeated string within the entire list. Here is what I got so far:

#-----------------
def Rep_String(inp):
words = re.findall(r'\w+', open(inp).read().upper())
commons = collections....
Thanks in advance if you are reading this code.
I recently submitted this code as part of an interview (took about 4-5 hours). Unfortunately, they did not like the code and I received a form rejection email without any sort of feedback. However, I am committed to improving my code and I would li...

As a Rust beginner, I would like to know how I could improve the following points considering the function below:
Handling Path and PathBuf types correctly;
Performance;
Rust writing style in general.
Here is the function, decorated with a full working example:
