If someone is sleeping like a log, they are sleeping very deeply without lots of tossing and turning.
并不是如此！這要表達的是祝福某人在夜晚睡覺時能有一個好夢。

Perhaps more importantly, how to recognize a kind of algorithm based on its properties and know what class it belongs to. This is a hint. If you like, leaning towards the next quiz, that you oughta be able to say that looks like a logarithmic algorithm because it's got a particular property. That looks like an n log n algorithm because it has a particular property.
也許更重要的是,如何根據(jù)一個算法的特點將其辨別出來,并且知道它屬于哪一類算法,這是一個提示，就對于接下來的測驗來說,如果你喜歡你可以說它看起來像一個對數(shù)算法,因為它有一個特定的性質(zhì),那個看起來像一個n，log，n的算法,因為它有一個特定的性質(zhì)。

and we like log algorithms, because they're really fast. A typical characteristic of a log algorithm is a pro-- or sorry, an algorithm where it reduces the size of the problem by a constant factor.
并且我們也很喜歡對數(shù)算法,因為它很快,對數(shù)算法的典型特性是高速，哦，抱歉，是他能以常數(shù)因子的速度,降低問題的大小，很明顯。
