PROFESSOR: All right. Good. So we can fully believe what our calculations were now, which is a nice thing to do.
教授:好了,我们现在可以,完全相信我们的计算结果了,多么美妙的一件事。
And we can calculate that with the formula that we used, which was just n minus l minus 1 equals the number of nodes.
这个我们可以用我们以前用过的那个公式来计算,也就是节点数等于n减去l减去1
And just as a fun aside, we also realized as computer scientists that sometimes technology is not the answer.
抛开趣味性不提,我们意识到作一个,计算机科学家来说技术,并不是我们要的最终答案。
OK, and that leads now to an interesting question, which would be, "How do I build a mechanical process to capture that set of computations?"
好,现在出现了一个有趣的问题,就是“我怎么样才能建立计算机程序,去捕捉一系列的计算呢?
