Now, as an aside, there's another couple of layers at the very top above the stack and above the heap, but below the tech segment and those are called initialized data and uninitialized data.
题外话,在堆和栈的顶端,还有好几层,但是在技术段之下,他们被叫做初始化数据和未初始化数据。
He has data for a very long time period, 1802 to 2006, for the U.S.
他的数据是采用美国从1802年到2006年,相当长的一段时间。
> Okay. Well, this code allocates a new integer pointee and this part sets x to point to it.
>,好的,呃,这段代码分配一个新的整型指针数据,这部分让x指向它。
You try to design actually I'm going to come back to that in a second. It's like you're trying to use a hash function that spread things out pretty evenly. But the places you store into in those lists may have to themselves have a small list in there, and when you go to check something, you may have to do a linear search through the elements in that list.
你尝试着去设计,实际上过会儿我会回头讲解这个问题,类似于你需要用一个哈希函数,非常平均的将物体分发出去,但是在列表中你数据,映射到的地方可能会有自己的一小段列表,当你回头查找数据的时候,你可能需要在那一小段列表中做线性查找。
You could take weights on people measured over a period of many years and look at the variability over time in weight and then link it to things like heart disease and cancer, and I'll come back later and talk about the results of that particular study.
我们还可以得到人们很长一段时间里,每年的体重数据,观察体重随着时间变化的变动,并将观察结果与心脏疾病和癌症联系起来,我等一下会告诉大家这项研究的结果
