I've been coding a Gameboy emulator in C for some time(seems like a common project for people). It's reasonably functional and has some MBC1 support, but has some minor graphical glitches still. I've coded on and off for a long time, but consider myself still very much an amateur and have no pr...
Following up on my implementation of Cryptopals Challenge 1, this is my solution to Challenge 3.
Single-byte XOR cipher The hex encoded string:

Fairly new to Python, and I have been doing a few Edabit challenges, to better help with my problem-solving. I have just completed a some what semi-difficult challenge, and I was hoping for some feed back.
The challenge itself:
Create a function that takes an imgur link (as a string) and ex...
This the first time to post on code review, I'm not even sure if this is the right place to post this:
In the following code I use sequelize.js to create 2 tables (users and tasks) which have many to many relationship.
I create a user and then check for tasks: if a task already exists, assign i...
Question: Write a program to swap pairs of characters of a String. In
case of odd number of characters last character should remain
unchanged.
Examples:
Input: HI
Output: IH
Input: hello there
Output: ehll ohtree
My Code:
import java.util.*;

I am using the advection-Diffusion equation in 2D to study animal movements.
∂N/∂t=∂/∂x (D ∂N/∂x)+∂/∂y (D ∂N/∂y)-∂/∂x (uN)-∂/∂y (vN)-zN
I was inspired by the work of Sibert, J.R.,et al 1999 (An advection–diffusion–reaction model for the estimation of fish movement parameters from tagging data,...
Need xUnit tests for following class methods:-
I am not sure how do I write a unit test case for this.
This is pretty much difficult for me.
There are few methods which I am not sure how to test or mock as there is await method which needs
input parameters but they are not available as the...
My team and I have designed a new api to manage user account details.
I am in need on some feedback and critics on our design.
The user account will be created by another API...

This is an implementation of a general Purpose Parser/Matcher that can operate on any input stream of objects and will return all possible combinations.
In this case I do not value performance that much but if you find something major, tell me.
This does by design no optimizations before parsin...
I created this simple react application as coding challenge for a job.
The README file in linked codesandbox describes the tasks.
It was basically an empty table and I created the components and helper logic to achieve the tasks (which is to display dynamic data and to provide sorting capabilit...
A palindromic number reads the same both ways.
The largest palindrome made from the product of two 2-digit numbers is 9009 = 91 × 99.
Find the largest palindrome made from the product of two 3-digit numbers.
<?php
function isPalindrome($input) {
return (string) $input === strrev($input);

Summary: The basic calculator which allows the end-user to calculate the value by evaluating the math expression string. It supports all the main arithmetic operators, also extended by modulo and exponent operations. Evaluation does follow the classic arithmetic rules and precedence and does take...
i'm looking for quick code review. I want to print screen from my UWP app. I created a service for printing but i need to provide UIElement to use it. The best way (IMHO) is to pass UIElement in codebehind. I did it like this:
public sealed partial class ViewPage : Page
{

I am trying to implement a solution to the following problem -
Given a set of numbers, check whether it can be partitioned into two
subsets such that the sum of elements in both subsets is same or not.
Input:
The first line contains an integer 'T' denoting the total number of

/*I want to change the input to ensure that integers, not letters, are inputted by the user, and that the program understands the numbers out into the machine (which would understand the number and recognize that number as a certain GPA grade). I only understand how to put in letters and plus/min...
I'm using MediatorLiveData class because seems useful to update the source of a LiveData object.
I mean, the majority of tutorials that I've found on internet just use Livedata or MutableLivedata without a dynamic source, in example:
fun search(/*no input params*/): Call<List<Person>>
But in m...
I would like to compare the min/max values of a time-series with a test time-series. Additionally, I would like to compare the time of the "peaks". However, I'm having trouble extracting these features from a Pandas DataFrame.
Given the following data:
