So I'm going to solve this by enumerate and check, which is an example of what's called a brute-force algorithm.

你懂的,所以我得靠列举和检验来解决这个问题,这就是我们说的穷举算法。

So this is a nice little search-- sorry, a nice little sort algorithm . And in fact, it's relying on something that we're going to come back to, called the loop invariant.

恩，这是一个很棒的小搜索，抱歉，和很棒的小排序算法，事实上，它依赖于一些我们要回顾的东西,被称作循环不变量。

And so ease of implementation is actually a very compelling -- metric against which to measure-- -- do you mind toning my voice down a bit-- is a very reasonable measure against which to measure the quality of an algorithm, right.

如此简单的实现实际上是一个很牵强的,度量，与之相对的衡量是-,如果你们不介意，我降低点音量-,是一种用来度量算法质量的,合理的方法。

To be taken with a grain of salt is its claim to possess a secret-sauce algorithm that spits out a warning when a stock is likely to tumble.

FORBES: Monday Morning Quarterbacks

Aside from the relative ease with which attackers guess passwords, once they have stolen the list of usernames and hashed ( a one-way algorithm used to hide data) passwords, the attacker just checks a dictionary of hashed words against the hashed passwords to find matches.

FORBES: Perhaps Sony should consider strong authentication?

Roth, aided by a Harvard graduate student and a young economist at Columbia, redesigned the system using a version of what's known as a deferred-acceptance algorithm.
