Or take this value out of memory, run it through some other simple operation, stick it back in memory.
或者从记忆存储器中取出一个结果,在类似的操作中运行,再插回到存储器中。
Give you some examples. What have we talked about? We've talked about things like using comments to highlight what you're doing in the code, to make it easier to debug.
给大家举些例子,我们一直在强调什么来着?,我们讲过要用注释来说明,你在代码中进行的操作,以便于调试。
Practically, sons didn't all live in the same place with their father.
实际操作中,儿子并不全都和父亲住在一起。
Nevertheless, to secure the distinction in actual practice, to say, "Okay. This is the meaning and now this is how I'm going to make it significant" -well, it seems unlikely indeed that this is something anyone could ever accomplish.
然而,若在实际操作中,你试着去体现这个区别,你会说,好的,这是意思,现在我来将它变成意义“,可是,实际上似乎谁都,无法完成这个任务。
Only the operating system has controlling of byte zero NULL in the computer's RAM and so if a function ever returns null, aka zero, well, something must have gone wrong because that can't possibly belong to me that memory because by human convention zero is owned by the operating system; not by a program I wrote.
只用操作系统在内存中能够控制,字节0,并且如果一个函数返回,或者说0,好的,可能出错了,因为那可能是不属于我的内存,因为惯例上,0是由操作系统拥有的,而不是由我的程序拥有的。
How do I operationalize that in this game?
我在这个博弈中应该如何操作呢
And we're going to see, well all right.
在这一块程序中做的操作。
So we're to assume we can get to any piece of data, any instruction in constant time, and the second assumption we're going to make is that the basic primitive steps take constant time, same amount of time to compute. Again, not completely true, but it's a good model, so arithmetic operations, comparisons, things of that sort, we're all going to assume are basically in that in that particular model.
因此如果我们假设在恒定的时间内,我们可以取得任何一块数据,任何一种数据结构的话,我们要做的第二个假设就是,基本的原始操作计算花费的时间是恒定的,这个假设也不是完全正确的,但这个模型其实挺不错的,因此算法操作,比较,这一类的事情,我们在这个特定的模型中都假设是基本的,操作,花费的时间是恒定相同的。
So really, the rule of thumb if you think back to Scratch is -- that any time you write a statement -- -- something that does something in one line of code -- you generally need the semicolon there.
实际上,根据经验,你们回忆一下在Scratch中,任何时候你们写一条语句-,处理一些操作的一行代码-,你们通常需要在那里加个分号。
And in Python the expression is, operand, operator, operand, when we're doing simple expressions like this, and if I give it to the interpreter, it gives me back exactly what you'd expect, which is that value. OK?
在Python中表达式就是,运算对象,操作符,运算对象,当我们处理这样的简单表达式的时候,我把表达式传给处理器,处理器给我返回了我想要的结果,对不对?
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。
