These things run for variable amounts of time because they take input, a list of size of some amount.

而这一段的执行时间是可变的,因为它们需要输入一个包含一些元素的列表。

It was a complete waste of time, unless the goal in life was simply to pester the user for some input.

刚才的时间就完全浪费了，除非那个唯一的目的,是简单地纠缠用户索要一些输入。

Another way of saying it is, if I, for example, 10 increase the size of the input by 10 10 the amount of time increases by 10.

另一种说法就是，例如，我把输入的规模增加0,解决花费的时间也会增加。

I'm much better having an exception get handled at the time of input than to let that prop -- that value rather propagate through a whole bunch of code until eventually it hits an error 17 calls later, and you have no clue where it came from.

不是我期望的格式,这时我最好有一个异常处理,而不是让其传下去,这个值传到代码的整个分支,最终会导致一个错误17调用的发生，并且你不知道这个错误是哪里来的。

So the running time of the problem where the input is T of size N as expressed here formulaically, T of N, the running time of an algorithm, given an input of size N. You know what?

因此一个输入为N的问题的运行时间,在这儿的公式表示为，如果输入为N，那么此算法的运行时间,是多少呢？

I'm going to use the CS50 Library instead for user input I'm saying say something then I'd get a string from the user and I call time s1 and then I say, say something, s2 and then I get another string from the user and call it s2 and apparently this program's purpose in life is to tell me yes or no the user said the same thing both times.

然而我使用的是CS50库来获得用户输入,我说点什么，然后从用户那里获得一个字符串,并把它叫做s1，然后我说点什么，然后从用户那里获得一个字符串，并把它叫做2,这个程序的最终目的是,告诉我两次用户输入的是不是同样的东西。
