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

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

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.

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 knew there was something about 'Sun Medallion,' in particular, because I just had to record it the second I wrote it.

I was a roving guard on the Lowell Hebrew Community Center's girls' basketball team all through high school. My specialty was stealing the ball, but my only shot was a lay-up.

All these corporations don't want their drivers to ruin their image, so you can't say what you think. You're basically not allowed to have a personality. How can you have any heroes if you don't allow personalities?

Bullying is not gonna stop, but we can at least be confident enough to stand up to it.

Women now have to put so much attention into their careers, and not many families can pull off a single income.

Dibakar and Shekhar have the vision that we would associate with European cinema. They leave their actors on their own to give a personal narration on the screen.

Because the stores worked, franchisees wanted to build more stores. If your model works, folks who are happy with it will buy out the ones who aren't happy.

Nobody minds having what is too good for them.

Autism is the fastest growing developmental disability in our nation.

You look at women like Lena Dunham, you look at how women are kind of crafting their own space on the screen. I want to add to that.

Making social comment is an artificial place for an artist to start from. If an artist is touched by some social condition, what the artist creates will reflect that, but you can't force it.

From being a teacher and educator, I see the state of the music through the eyes of an 18-year-old coming on to the scene, and we want to make sure it stays intact. With my generation, it's our duty to do that.

I'd like a telescope, but I probably wouldn't look at the stars that often. I'd definitely be looking into people's flats most of the time.

One of the most attractive things about the flowers is their beautiful reserve.

Tom Hanks is fantastic - he is one of my dad's good friends, and he's very warm and funny.

The activity of being a husband a father those are roles too but underneath them is the spiritual center that connects us all and thats whats most important.

We wanted Nike to be the world's best sports and fitness company. Once you say that, you have a focus. You don't end up making wing tips or sponsoring the next Rolling Stones world tour.

Above all be of single aim; have a legitimate and useful purpose, and devote yourself unreservedly to it.

Daily ripples of excellence over time become a tsunami of success .

Happiness seems made to be shared.

Music is the best way for me to say I love you.

I really believe in the philosophy that you create your own universe. I'm just trying to create a good one for myself.

Part of my mandate is to curb corruption and streamline a cumbersome, graft-ridden bureaucracy, to put resources where they will provide the clearest results, and to untangle a complicated regulatory environment.

I still listen to a lot of the classics from Bob Dylan and John Martin, but I love electronic music as well. I'm a big fan of an Australian DJ and producer called Flume, who I think is incredible. He should be more successful in the U.K.!
