We were asked to implement a program that calculates the number of Fermat witnesses and liars for odd numbers greater 1. This involves Fermat’s little theorem.

"""Basic usage:
$ python fermat.py 7

I wonder if it is possible to transcribe this js framework for architecture in Knockout.js framework.
Using methods like this:
newMessage: function (message, userName) {
*//Todo*
};
See this:
var chatR = window.chatR = {
hub: null,
user: null,
init: function () {

I have made a Skyline query solver which for now can solve the query with two different algorithms.
The first is Block-nested loop (BNL) and the second is Sort filter skyline (SFS). The two are extremely similar. I will explain the basic things that are needed to review the part I am interested ...
This website has a useful list of the various iDevice models. And the "identifier" column is helpful for any iOS developers, as this is the string you can fetch in your application to determine what kind of device your program is running on.
However, for reasons, I am interested in determining ...
For all it's worth, I have ran the command line in Terminal with a few devices.

I have a 3GS somewhere but I can't find right now. I'll edit my answer if/when I find it.
I'm actually building some kind of framework to promote code reuse without over-reusing it. Besides, sometimes as it occurs with generic types, one expects type parameters to be constrained for the purpose.
In MVP, those constraints translate well enough.

I get the response object from other project library class which I cannot modified. How should I refactor this code so that I don't have to check for NullPointerException, ArrayOutOfBoundException or using many if checking to check object is null and array is not empty?

The following code compiles correctly:
public ContextStatus Commit(string userName)

var status = new ContextStatus();
var task = Task.Run(async () => { status = await CommitAsync(userName, new CancellationToken()); });
task.Wait();

I have been working on a python game (hangman). There's one part I can't get to work.
I want to update the guessed formula so far using a function. For example, if the formula is 123456 and the user guesses 1, the function should add the 1 and print

I have this huge chunk of code, I want to know if there is any better to write this code?
Or am I too paranoid that I check every MongoDB query for error??
The logic is here:

Book = book info
Query book collection of the user, if found find the book info f...
If I want to use the same class for any data type, then I might have used templates.
And then if I have a class
class A
{
int x;
public:
void setx(int a)
{
x=a;
}
};
Then in main() function,
A a;
a.setx(10);
StackusingList<A> *s2= new StackusingList<A>(2);
s2->push(a);
cout<<"new\n";

I am writing a REST API for a pretty complex legacy system, with multiple applications and systems accessing it.
The problem is that the different systems all know different things about the data.
For instance, for the orders, the website looks for the ID (which is not the DB line's ID), and th...

Yes, there is an easy way:
IntStream.iterate(0, i -> i + 2);
With as usecase:
IntStream.iterate(0, i -> i + 2)
.limit(100)
.forEach(System.out::println);
Which prints out 0 to 198 increasing in steps of 2.
The generic method is:
Stream.iterate(T seed, UnaryOperator<T> f);
