Exercise 1
Please implement code and data structures that read the files
src/test/java/resources/people.csv
src/test/java/resources/relationships.csv
and use them to build an in-memory data structure that represents the people in the file and their relationships with each other.

In a few hours I threw together this little text-based java game. Pretty much you're managing a forest and have to try and keep it together while keeping enough of a profit to move forward.

import java.util.Arrays;
import java.util.Scanner;
import java.util.concurrent.Thread...

Pattern 2 :

String password;

I often come around a requirement where we have to perform a repetitive task on the user's screen (for eg, updating a counter like flash sale/ live class timer, autoscrolling the banner, etc) .
I have written this small file which performs a basic task of pressing a button every 2 seconds for a t...
For example, given [10, 15, 3, 7] and a number k of 17, return True since 10 + 7 is 17.
How can I improve the below solution?
from itertools import combinations
def add_up_to(numbers, k):
c_k_2 = list(combinations(numbers, 2))
return any([True for pair in c_k_2 if sum(pair) == k])
This is a follow up to my previous post.
I've used a BCrypt library to create a key from the passed in password. I then separated out the salt from the hash. The encryption is done using the salt concatenated to the hash, but only the hash is returned to the user. The salt is prepended to the ...
I was seeing alot of machine learning applications calculate fitness via 1.0 / x. Division in computers is slow so I came up with a version that is about ~36% fast on my architecture (-march=x86-64).

#include <numbers> //std::numbers::log2e

I don't participate as often as I used to on this site. But I still have about 1k reviews on my account. So I was sort of surprised when I saw this pop-up today:
My questions are:
Is this a bug? Is this a new feature that everyone sees?
But more importantly, have I done something wrong during r...
I'm making my first card game with React.js and I'm stuck at one point.
How can I display the total win count?
For example, if in this game the computer scored 10 points and won, and in the next 15 more points the global counter should show 25.
App.js
import React from "react";
import './App.css'...
