index value

基本解释

They specify the initial value of the index for the iteration and the index value at which iteration should cease, respectively.
它们分别指定迭代索引的初始值以及迭代索引的终止值。
The ending index value of this set of elements can be calculated only by adding up the total number of values that occurred in all preceding slices plus the current slice.
计算这个元素集的结束索引值的惟一方法是，求出前面的所有片和当前片中出现的值的总数。
However, if there are many duplicate rows per distinct index value, and the associated table is highly clustered, the added costs of joining through the index can be slight.
然而，如果每个不同的索引值都有许多重复的行，而所关联的表是高度群集的，那么通过索引添加的连接成本可能很低。

To help determine what a country's brand value is, Anholt created the Nation Brands Index, a survey that ranks 50 countries on how they are perceived overseas.
Ah-ha. What does that say to do? It says, 3 gee, make min index point to there min value be 3. Change j. Is 6 bigger than 3?
啊哈，这该怎么处理呢？,让MinIndex指向那里，MinVal是,改下j值，6比3大么？

OK. What does that say? I'm going to change MinIndex min index to also point there n value is 8, j starts off here, and I say, OK, is the thing I'm looking at here smaller than that? Yes.
好的，这意味着什么？,我打算交换，让它也指向那里，MinVal是8，j从这里开始,我要找的值比这个小么？是的。
