Now we add one to the counter i and repeat.

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.

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

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.

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.

'American Playhouse' is very supportive of writers. That's really why writers like to write for 'American Playhouse' for very little money. They care about making your play, your script, not some network production. We're treated like playwrights, not like fodder for some machine.

Texting is addicting. Once you get emotionally involved with constant outside stimulation assaulting your brain, it is hard to stop looking at your machine every two minutes. Without rapid fire words appearing on a screen, you feel bored, not part of the action.

Intuition isn't the enemy, but the ally, of reason.

There's so much to learn about acting and performance in general... I mean, acting is a very complex art, and there are a lot more theories and methods and techniques to it than I think anybody would think.

When we become a really mature, grown-up, wise society, we will put teachers at the center of the community, where they belong. We don't honor them enough, we don't pay them enough.

The threat or fear of violence should not become an excuse or justification for restricting freedom of speech.

Again, both literature and philosophy work by appealing to certain reigning idols.

A daily dose of Nietzsche goes a long way.

The celebrity sense of writers is something which is very tempting... But the enthusiasm comes from the fact that it's such a natural activity, storytelling.

Tomorrow is a new day if you begin it today.

Information is expanding daily. How to get it out visually is important.

Same with souls. They can't survive without a body for long.

Talking isn't doing. It is a kind of good deed to say well; and yet words are not deeds.

Honesty is the cornerstone of all success, without which confidence and ability to perform shall cease to exist.

I constantly have anxiety about being the lead of the show. I don't talk about it because it scares me. But I've always wanted to be part of something where I could work on a character in such a big manner, and you get offered that with all the trappings of being the lead of the show.

Well, I'd probably go for any work I could get.

In the studio, if things go wrong, you stop things and fix them. I have never been in a recording studio, really, where the people in the booth were not interested in making a very good album. It's often a light-hearted atmosphere but serious at the same time.

No two Christians will ever meet for the last time.

I'm not claiming that we are the only guys who are going to succeed in the cloud. Others can succeed as well, just like in the previous generation.

I totally related to Cole Porter's magnetic pull to any piano that was in the room, which he was famous for doing, as was Gershwin. You couldn't drag them away from a piano.

People have a misconception that the tobacco epidemic is a thing of the past. Tobacco still kills more Americans than any other cause.

I want what's best for our country. I'm not sure I can figure that out.

Don't have good ideas if you aren't willing to be responsible for them.

If you are a man of dependability you are worth more than if you were clever.
