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

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.

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.

When humans behave murderously, such as inflicting senseless slaughter of innocents in warfare, we like to blame it on some dark, 'animalistic' instinct.

Reading makes you smarter. It really does.

One can hardly be Indian and not know that almost every accent, which hand you eat your food with, has some deeper symbolic truth, reality.

Going back and forth between Western Arabic and African countries clearly created the various musical backgrounds I could have and obviously influenced my professional attitude, my way of approaching both music composition and singing, particularly phrasing.

I've been very fortunate and met the guys that have become, basically, philosophers and have a kind of sensibility about life that's very precious.

Despite everything, no one can dictate who you are to other people.

Some people work hard in this business and become really popular, really big stars but they never receive an award from within the business. Somehow, when your colleagues and friends believe in you to the point of handing you an award it means so much more.

People do not win people fights. Lawyers do.

As coaches, we usually have plenty of changes from one year to the next. Sometimes it seems like it's at one position. Sometimes it's across the board. But this is really a part of every year that we have in coaching in the NFL.

I always want to be an actress.

Rule #1 of life. Do what makes YOU happy.

When you are young, do not get involved in steady dating. When you reach an age where you think of marriage, then is the time to become so involved.

The budget is not just a collection of numbers, but an expression of our values and aspirations.

The battle against cancer has made me strong. It's like winning a war! When I was diagnosed, I was told by doctors my kidney, liver and other organs could fail. It was tough. I didn't know if I could save my life. But I was positive, and because of that, the doctor told me that I would be a man who would never have cancer.

I'm so sick of hearing how there's no strong roles for women. I don't care about strong roles. I just want to see women who are characters! A nun, a serial killer, a housewife, as long as there's some depth there.

Growing up in a suburban home, the world seems so massive to you. It seems like cities are so big and so far away, and there's so much in them. So your imagination runs wild, instead of when you are born in the middle of Manhattan, you'd know, like, that this is the biggest city.

I play games.

Performance capture, for me, is finding the essence of a performance.

There is something so rewarding about dancing. It's almost spiritual - you let loose, you feel free, you get endorphins from the exercise.

I wouldn't mind doing a soundtrack someday.

There will come a day when I can no longer run. Today is not that day.

The two have to go hand in hand - the atmosphere and the music. I actually get rather worried if I can't see the music first. There always needs to be a mood, a feeling, a story, even if it is abstract. There's got to be a narrative to guide things before they're even created.

But we are strong, each in our purpose, and we are all more strong together.

My father had a brilliant scholastic record in high school and was awarded a college scholarship. Unfortunately he had to turn it down so that he could continue to support his family.
