"Inception" and recursion in the program

The dream does not know the body is a guest, a noon greedy huan.
----Li Yu "Surf the Sand"
This life wrong train, destined not to be with you,
A dream dream, my soul, chasing you to the afterlife ...
----a Taiwanese poetess.

Saw the inception of the Dream space. Inception English name literal translation is "establishment" meaning.

The hero can enter your dream, change your subconscious in the dream. This is the greatest danger is not clear which is the dream, which is the reality.

In reality, we often encounter such a situation, to their own bite to see whether it will hurt, or will not wake up.

The place where the audience is confused in the dream of inception is the dream. In your dreams, you can dream again.
There are similar concepts in computers. For example, recursion is the most typical application.

the so-called recursive-recursive is that you can call yourself in the method.

The following is one of the simplest recursion (of course it will be a dead loop, so the real recursion does not write this)

public void Sayhi () {
System.out.println ("hello!");
Sayhi (); Himself to call itself, would be called countless times
}
The above program, if you run, will eventually stackoverflow the stack overflow error.

One of the true recursive applications: to find the factorial of a number
public int fact (int n) {

if (n>0)
Return N*fact (n-1);
Else
return 1;
}

If the argument is 4, its call order is shown in Figure 1 below:

There are a number of examples of recursive invocations, such as Hanrotta problems and so on.

Hehe by the way, if you do not understand the inception of the space, then do not engage in software. Technorati Tags: Atixujie, java, PENGZJ, inception space, inception
