A good algorithm is like a sharp knife—it does exactly what it is supposed to do with a minimum of effort.
一个好的算法就像一把锋利的刀——它以最小的努力准确地完成它应该做的事情。
译文：聪明用错地方了，不如一辈子愚钝；交友不慎，错交朋友，还不如静下心来读书。赏析：聪明反被聪明误，聪明的才智用在正道，才能凸显它的价值，反之则会贻害无穷。朋友在于精，不在于多，狐朋狗友千千万，不如知己一人。
The land is our mother, the rivers our blood. We must protect her, for she is our life.
