"It's time to do what's right for America's working families and put aside partisanship, stop saying things that aren't true, come together as a nation, pass health insurance reform now this year."

In fact one of the frankly best things I ever did as an undergraduate was, perhaps fittingly, take this course pass-fail.
实际上我上本科时做的最得意的事,恰当地说,就是把这门课的成绩看成及格和不及格两种。
Linear algorithms tend to be things where, at one pass-through, you reduce the problem by a constant amount by one. If you reduce it by two, 1 it's going to be the same thing.
有问题么?,线性复杂度的算法,当进行了一个,常量级步数的操作的时候,将问题的规模缩小了一个。
7% 77% is class average and the standard deviation was 17% so you can see where things lie. 50% is a pass.
7是平均水平,标准偏差是%,这就是事情所在,50%就及格。
But sometimes you can pass multiple things inside those parentheses, and so you separate them by commas.
有时候我们可以往圆括号里填入多个参数,参数与参数之间用逗号分开。
So think about these things, don't pass over these details lightly, and don't take them for granted.
我们不应该轻易忽略细节,也不要想当然。
On the other hand, if you haven't been keeping up, I hope that you won't pass so I can tell you, look, you have to do things differently.
另一方面,如果你没有继续进行,我希望你不能够过,因此我要告诉你的是,看,你做的事分别很大。
If you pass a function in C, a value that it's not expecting bad things happen and bad things generally reduce to segfault.
如果你在C中传递一个函数,一个没有预料的情况将会出现,这个情况通常是段错误。
And in this case, we go from 8 to 4 to 2 to 1 three times and then on each iteration of this algorithm, each pass across the board I'm touching N numbers, so that means I'm doing N things, log N times.
在这个例子中,我们从8得到4,到2,再到1,是3次,在这个算法的每次迭代中,每一趟我都会操作N个数,也就是所我每次要做N步操作,一共要做,log,N,次。
