upper bound

基本解释

Doesn't need to be, so, what should I do about the upper bound here?
不必改下边界值，因此,我该对上边界值做个怎么样的改动呢？
Note that the demand for trains is unlimited, so a very large value is the upper bound on line 43.
注意对于火车的需求是无限的，因此在 43 行上我们使用了一个很大的值作为上界。
Range Queries allow one to match documents whose field(s) values are between the lower and upper bound specified by the Range Query.
范围查询允许你指定某个字段最大值和最小值，查询在二者之间的所有文档。

Oh, I could cheat and make, OK the upper bound a half, but that wouldn't be very honest.
噢，我可以像作弊一样,把上界扩大两倍，但这看起来没什么用。

So the basic idea was fine, but I failed to satisfy the initial condition that the answer had to be between the lower bound and the upper bound. Right?
因此基础的思想是对的，但是程序没能满足,正确答案在给定的区间内这个条件,对不对？

All right? If you run it, you have a sense of the upper bound, about how much time it's going to take to do this computation, so you're not going to get surprised by something showing up.
第一，这样做意味着没有意外了对不对？,你去运行程序,你已经大致知道运行时间的上限了，因此发生任何事情,你都不会吃惊了。

My best guess would be that their calculation gives us an upper bound and the actual effect will be above zero but lower than their number.
