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.

People who laugh actually live longer than those who don't laugh. Few persons realize that health actually varies according to the amount of laughter.

Ice Cube's the coolest dad. A lot of parents - a lot of kids do not think their parents are cool. Oh, no. My dad's cool... You know, I was born in 1991. That's when 'Boyz n the Hood' came out. So I've always see him on TV. I don't see everybody else's dad, you know. So I've always had a sense of, you know, he's cool. He's in the light.

The people of Israel are entitled, as is any other nation, to live in peace and safety.

In the truest sense, Christian pilgrims have the best of both worlds. We have joy whenever this world reminds us of the next, and we take solace whenever it does not.

Jay Townsend has offered, and I have accepted, his resignation from his position with my campaign. Now let's return to talking about issues that really matter to families: job creation, spending restraint and economic development.

If being recalled is the price for keeping one's promises, then so be it.

If you get a good comedy once a year, man, that's pretty good. I may be pickier than some, but still, there aren't that many movies that are really, truly, honestly that funny.

As treasury secretary, I don't see it as my role commenting on the dollar in short-term movements.

God not only plays dice, but also sometimes throws them where they cannot be seen.

Dreams look real, but they're in your mind, so you realize that the physical world is also a construction, which shows that the mind can affect reality in more ways than you can imagine.
