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.

My father always said, 'Never trust anyone whose TV is bigger than their book shelf' - so I make sure I read.

I gave my life to become the person I am right now. Was it worth it?

I'm trying to focus on my job as I see it, which is to write the next thing and to remain, to the degree that I ever was, a noticer.

Who made me laugh when I was growing was Chaplin and the Marx Brothers, and then moving on, there were so many that I was a writer for for many years: I was a writer for the Smothers Brothers, Lily Tomlin, then I started on 'Saturday Night Live' as the head writer the first year we started it.

Our Nation must provide sufficient access to healthcare, adequate benefits, and the supplemental resources our veterans were promised and so dearly need. We owe our heroes no less.

The truth is the real Christian experience is truly about repenting every day because there is no Christian that doesnt sin.

Studying the daily news can appear more interesting than the priesthood lesson manual. Sitting down to rest can be more attractive than making appointments to visit those who need our priesthood service.

I find that many entrepreneurs are trying to do everything when it would be cheaper and more time-efficient to delegate, even if there are monetary costs associated with that.

It's important for me to sell a product that works.

The race of mankind would perish did they cease to aid each other. We cannot exist without mutual help. All therefore that need aid have a right to ask it from their fellow men and no one who has the power of granting can refuse it without guilt.

Poorer people tend to watch more television because they can't afford other diversions.

My concentration and focus level tends to go down sometimes when Im in a bad mood.

Film gives us the luxury of deciding where the viewpoint of the audience is, and by knowing that, we can very effectively design around what is actually seen on camera.

Israel, contrary to most of the West, has a high fertility rate, so there's a lot of young people in Israel. Most families have three kids as opposed to one or two, so a big proportion of the population is under 30.

The influential man is the successful man, whether he be rich or poor.

I grew up in the suburbs and basically associate the suburbs with cultural death.

I think of myself more as a sportsman than I do an artist.

Anticipation makes pleasure more intense.

Entertainment for entertainments sake is the most expensive form of death.

Because of the Thames I have always loved inland waterways - water in general, water sounds - there's music in water. Brooks babbling, fountains splashing. Weirs, waterfalls; tumbling, gushing.

In raising my children, I have lost my mind but found my soul.

History was a hobby for about, oh, 20 years before I got into print.

Real relationship is gritty and earthy, the stuff that life is made of.

There's going to be a flood of opportunities right now but I don't think I could really talk about them.
