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.

In my bachelor days, the priority wasn't learning to cook.

People were a little leery when I was doing the press for my last album 'Rumble Doll,' yes. It's always that thing that this is a dilettante or a pet project.

Our reactor actually burns nuclear waste as fuel. So not only is it safe and powerful, it solves an important issue: It actually reduces nuclear waste instead of creating. It's the reactor of your dreams.

We all know how funny Morrissey is. Actually, you know what? I say that sarcastically. His songs are some of the funniest songs I've ever heard in my life. I mean, really. I mean, not that the 'Girlfriend in a Coma' is, like, really funny.

You don't know who you messing with man, I slap people for fun. That's what I do man! You wanna play rough, huh, I kill for fun!

There was a big question as to whether or not different generations have grown up differently.

It's a no-win situation with politics; it's always going to be stressful. I'm more into the comedy of life.

I'm not a morose person; it's just that my best songs reflect on the sadder aspects of life.

The heart, like the stomach, wants a varied diet.

The important thing is staying together if you want to do something special.

The ability of the 1 percent to buy politicians and regulators is nothing new in American politics - just as inequality has been a permanent part of our economic system. This is true of virtually all political and economic systems.

We live in diverse communities with all sorts of people from all sorts of different backgrounds. The more our entertainment can be a reflection of the world we live in, the better it is for all of us.

Fanboys are a creator's blessing and curse. If a fanboy likes you, they love you. Obsessively. If you cross them with some plot point or story direction they reject, expect to be wholly and continually eviscerated across the Internet.

The financial capital is being concentrated by corporations, institutional investors, and even our pension funds, and being reinvested in companies that repeat this process because it provides the highest return on that financial capital.

Religion has done love a great service by making it a sin.

I'm who I am. I'm confident. I think it's weird if you're not confident.

We must insist on assimilation - immigration without assimilation is an invasion. We need to tell folks who want to come here, they need to come here legally. They need to learn English, adopt our values, roll up their sleeves and get to work.

I want to put my name in history. I love history.

In our pledge every day, we pledge one Nation under God with liberty and justice for all.

I designed and developed an unbelievable number of applications early in my life.

While the debate over banned books usually seems to happen just outside the gates of government, it takes on a new danger and urgency when legislators get involved. Their actions cause voices to be silenced both inside and outside the books. That's un-American.

A fine line separates the weary recluse from the fearful hermit. Finer still is the line between hermit and bitter misanthrope.

I support free trade, and so does Donald Trump.

Social media stars are kind of taking the traditional route, like movies.
