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.

I think it's fantastic when the young enrage their elders. I really do believe that if it's too loud, you are indeed too old, and that if it has been standing for too long, it needs a thorough inspection.

Things have never been more like the way they are today in history.

I wanted to do Playboy to get across the same ideas I'm singing and writing about these days. It's all about proving that a woman can defy stereotypes.

If you go out to Hollywood you'll find a lot of fantastic plastic people there in the business and a lot of people in life generally. They find it so hard to be themselves that they have to be plastic.

Every country that's ever been the most powerful country in the world ceases to be the most powerful country in the world at some point.

Every actor's deepest desire is to reach a huge audience. So, I don't look down upon commercial cinema... there's a beauty in it that you understand sooner or later.

I like the idea of bringing cartoon characters to life... and although the Americans have already attempted this, their culture is not sufficiently humane to make it work.

I ultimately got into robotics because for me, it was the best way to study intelligence.

It is only God who can satisfy the soul.

Indictments of any kind are serious. That being said, let's not forget that an indictment is not a conviction. We still have due process in this country.

In the world of the celebrity, the hierarchy of publicity has replaced the hierarchy of descent and even of great wealth.

You can use your real identity, or you can use phone numbers for something like WhatsApp, and pseudonyms for something like Instagram. But in any of those you're not just sharing and consuming content, you are also building relationships with people and building an understanding of people.

Those that don't believe how small my work is should just come along and see it for themselves.

It's time we permanently repeal the tax on possessions that people leave to their children.

Wherever you've got a state church, you have empty churches.

The mania is like wasps under the skin, like my head's going to explode with ideas.

I just felt being part of my peer group so strongly. I was immersed in teen culture, but not taken in by it.

For me, my secularism is, India first. I say, the philosophy of my party is 'Justice to all. Appeasement to none.' This is our secularism.

If you arent failing you arent trying.

You can get the true essence of New Yorkers by just hanging out in Central Park.

I live in L.A., so I go to basketball games. But I love baseball.

Marilyn Manson is a mockery of American pop culture.

When making plans, think big. When making progress, think small.

Man should be master of his environment, not its slave. That is what freedom means.
