现在我乘以运算符的大小,之前我们看到的。
-
Take your own weight in your mind and multiply it by three.
想一下你们自己的体重,然后再乘以三
-
Now this happens to be what we would call a linear process, because the number of times I go around the loop is directly related to the size of the argument. If I double 2 the argument, I'm going to double the number of times I go around the loop. If I increase it by five, 5 I'm going to increase by five the number of times I go around the loop.
这恰好是我们会成为,线性复杂度程序的一个例子,因为我要执行循环的次数是,和输入的参数的大小直接相关的,如果我将这个参数乘以,那么我就要将进行循环的次数也乘以2了，如果我把参数加上,那么循环的次数也要加上5了。

How do we do that correction? When I first tried this, I thought, fine I'll multiply by 365/60, but I forgot this is a leap year.
那么怎么换算呢,我第一次试的时候,我想,我乘以365/60,但是我忘了,今年是闰年
-
Can I multiply the ? by the 4 just to save myself some time?
我先算?乘以4吧,这样省事儿
-
So multiplying a vector by a number means stretch it by that factor.
所以用数字乘以矢量,就相当于将它伸长了相应的倍数
