In particular, it really helps to understand the ideas in algorithmic efficiency and Big-O notation.

特别是，算法效率和大0符号能帮助你真正的理解你的想法。

Big-O notation: computational complexity theory USES big-O notation to describe how input-data size affects an algorithm's use of computational resources.

Big - o notation：计算复杂性理论使用大0符号描述输入数据大小如何影响计算资源对算法的使用。

Constantly asking if x in otherlist runs into geometric big-O inefficiencies; marching in parallel between two stably-sorted lists is more efficient. For example

不断地检查 if x in otherlist 会导致效率成 big-O 式几何级数递减；在两个固定排序的列表之间进行平行匹配的效率要高得多。

N --O So we introduced this notation big O which generally refers to worst case.

的平方。，So，，N，squared。,这里我们介绍一个符号,它泛指最坏的情况。

So I went into this knowing that this had to be a big old 10 o'clock--well, its 9 o'clock--drama with broad appeal.
