"This is a partial solution that appeals to people who want a quick fix and it is not going to solve the problem, it will not prevent the recruitment of terrorists we have seen.

And the solution to this equation looks like this where it is written in terms of a quantity called a wavefunction.
这个方程的解法是,看起来像是写成数学符号就是,波函数。
There is obviously no magic solution to this question but the best answer I know of is Socrates.
这个问题,没有神奇的解答,但我认为最佳的答案是苏格拉底。
OK, so what have I done? I just added a little bit more now. I'm now running through a pair of loops. Again notice the encapsulation, that nice abstraction going on, which is what I want. Once I get to this stage though by the way, there might be more than one solution.
我现在运行了一对循环,再一次注意这个封装,抽象得很好,这就是我想要的结果,我按这种方式走到这一步的时候,可能会有多组答案。
Well, we know one solution to this is the following.
我们知道一种解决办法,下面会提到。
This is where the solution, by the way, to bringing together--and you could write this down-- to bringing together all the warring countries and religions of this planet is an alien attack.
顺便告诉大家,这个办法,是让…你们可以写下来-,让敌对国家合作的方法,让地球上的宗教合作的方法就是外星人袭击。
So always amazing to us how we go into the problem, our eye or mind can see one class of solutions, but the math will tell you sometimes there are new solutions and you've got to respect it and understand and interpret the unwanted solutions, and this is a simple example where you can follow what the meaning of the second solution is.
解决问题的方式总能让人惊喜不已,我们的眼睛或思想可以看见一类解,但数学有时会告诉你还有新的解,你不能忽视它,而是解释这些不期而至的解,这只是一个简单的例子,由此你可以理解第二个解的意义
So this is version two of the swap function and, in fact, it is almost identical, this is before, this is after, before, after and it looks like the solution to this problem that we've been revisiting a couple of times now is just to do what?
这个swap函数的第二个版本,实际上,这几乎是一样的,这是之前的,这个之后的,之前的,之后的,这看起来像是这个问题的解决方案,我们一直多次访问它,目的是什么呢?
