I'm trying to do a simple CMS with PHP from scratch using MVC structure.
Yesterday I posted this:
PHP Login System with persistent login
Which is a login system using PHP and it works but it has a handful of problems regarding the OOP aspects of it.

I am new to C++ and this is my first program. The objective of this program is to fully complete the sequence called the Collatz conjecture.
It concerns a sequence defined as follows: start with any positive integer n. Then each term is obtained from the previous term as follows: if the previ...
Below is the working code but it can surely be simplified with some sort of changeCol() and changeRow() functions, or perhaps a single function?
$(document).ready(function(e){
let keys = {};
let selRow = 0;
let selCol = 0;
//set initial highlits
$('[data-x="0"]').addClass('...
the question is like this:

Exercise: Using Arraylists create a program that makes divisions between two very large numbers (numbers greater than 10 digits).

I am completely new to programming. I am trying to write a code that will give a 1ms delay, using a loop. I have been researching on the internet and found the following:

My background is primarily in C#. Though, I've gotten comfortable with JavaScript, I feel that stylewise my JS code looks more like C# code.
Does the following code's style conform to "standard JS style"?

Problem Statement: Given a sequence of integers as an array, we have to determine whether it is possible to obtain a strictly increasing sequence by removing no more than one element from the array.
Example
For sequence = [1, 3, 2, 1], the output should be

Following rules are defined:

foo(b,[],[]).

The goal is to get a list of lists, that contains all of those atoms (a, b, c and d) without duplicates, e. g. [[a, b, c],[d]].
The sublists in this list have to be "valid", that means that each element in ...
