This works for both positive and negative numbers:

private static bool isEven(int number)
{
	bool result = true;

	while (number < 0)
	{
		number = number - 1;
		if (result == true)
			result = false;
		else
			result = true;
	}
	while (number > 0)
	{
		number = number - 1;
		if (result == true)
			result = false;
		else
			result = true;
	}
	return result;
}

Output:

isEven(4) = True
isEven(5) = False
isEven(-4) = True
isEven(-5) = False

True. I ordered a book from them last week; it arrived in 2 days. Everywhere else, including Waterstones, was “oh we might be able to get it out the door sometime next year, if we can be arsed” so Amazon got the order.

Civilised countries like the UK and other European countries. Technically it’s not free because it’s paid for by taxation, but it’s free at the point of use: if I go and see a doctor, I don’t get billed, but I do pay 9% National Insurance tax.

I’d be interested to know how I can pay my electricity bill with my free healthcare. Also I need to go to the supermarket today; how do I convert free healthcare into a trolleyful of food?

Maybe it’s a Samsung phone and a “Made in USA” sticker, shipped in as components and stuck together in the USA, thus fulfilling both “designed” and “made” in USA even though there are some foreign-made components (2). Then onshore those components bit by bit until the process is complete.

Technically that’s 100% buffering.
