Then if n is odd, we switch the first element and the last one.

Heap's algorithm generates all possible permutations of n objects.

It generates each permutation from the previous one by interchanging a single pair of elements; the other n-2 elements are not disturbed

First set a counter i to 0. Now we perform the following steps repeatedly until i is equal to n.

We use the algorithm to generate the (n-1)! permutations of the first n-1 elements, adjoining the last element to each of these.

Thus we generate all of the permutations that end with the last element.

If n is even, we switch the i-th element with the last one.

Note that there's no difference between n even and n odd in the first iteration.

Now we add one to the counter i and repeat.

In each iteration, the algorithm will produce all of the permutations that end with the element that has just been moved to the "last" position.

A broken heart is just the growing pains necessary so you can love more completely when the real thing comes along.

In the scope of a happy life, a messy desk or an overstuffed coat closet is a trivial thing, yet I find - and I hear from other people that they agree - that getting rid of clutter gives a disproportionate boost to happiness.

If you sing to the mermaids, they come when you're drowning.

Leftism seeks to undo most of the values that are distinct to Judeo-Christian religion.

I was a dispatcher, flat-tire fixer, changed the oil, fixed the fan belts. There was nothing too good for me.

I'm kind of one of these guys who wants to play everything once before it's all over.

Socrates became a trendsetter. Other philosophers, including Plato and Aristotle and Gus, quickly followed suit, dropping their last names too. And, for centuries after that there would be countless imitators including oltaire, Michelangelo, and, much later, Cher.

I think every person deserves two marriages, because you may not get the first one right. You really never knew. That's why divorce is so big. We all want it to last, but that's not always the reality of it.

My goal is to get another 30 years out of this business. So I need to figure out the fuel to do that. And so far, I think it's respect and quality and company, not celebrity or box office or stardom. It's not a sprinter's approach. It's more like a long-distance thing. You can stick around a lot longer if you kind of slow-play it.

Nothing has been left undone by the enemies of freedom. Every art and artifice, every cruelty and outrage has been practiced and perpetrated to destroy the rights of man. In this great struggle, every crime has been rewarded and every virtue has been punished.

I'm excited to watch slope style and halfpipe. And then, of course, when my events are done, I get to go to hockey, which is always entertaining. I also like figure skating. I think every girl grew up watching figure skating.

In every deed of mischief he had a heart to resolve, a head to contrive, and a hand to execute.

My arm came back just as quickly as it went sore on me in 1915. I awoke one morning and learned I could throw without pain again.

A girl without braids is like a city without bridges.

Bowling is not a sport because you have to rent the shoes.

Rather than love, than money, than fame, give me truth.

I've always recorded the same way. I put down as many ideas as I have, then strip them away at the mixdown. It's better to have too much music than not enough.

My introduction to the Brady book was an attempt to nail the exact same idea since Brady addressed the point. And since I write pornography, naturally, something of an obsession for me.

Adversity makes men, and prosperity makes monsters.

I have a strong disrespect for authority and for rules. Including gravity. Gravity sucks.

Books are the money of Literature, but only the counters of Science.

I lied for years and years. And the thing about lies and secrets is that they eat you alive from the inside. I would not wish that pain on anyone.

I love how a story can help someone discuss something they otherwise would not.

I don't desire happiness. I think it's a myth, and I don't think it's... and it makes you complacent. I feel very satisfyingly uncomfortable. I have the freedom to feel uncomfortable in the way I want to, is maybe a way to put it.
