http://en.wikipedia.org/wiki/Two's_complement
The two's-complement system has the advantage that the fundamental
arithmetic operations of addition, subtraction, and multiplication are
identical to those for unsigned binary numbers (as long as the inputs are
represented in the same number of bits and any overflow beyond those bits is
discarded from the result). This property makes the system both simpler to
implement and capable of eas... 阅读全帖 |

发帖数: 2697 | 7 stock price是real market的data，有交易价格变化才会更新数据，可以假设更新时间
单位是在秒这个数量级的
具体处理只需要保存有可能是Max和Min value的数据 其他update的时候可以discard掉
最坏情况下确实需要保存12个月内所有的数据 |
|
f*********m
发帖数: 726 | 8 能避免用这个12个月的数据数组吗？
我觉得每秒都需要更新吧，至少每秒要删掉超过12个月的数据。
Max和Min value的数据需要两个变量，同时还要记录这两个变量在12个月数据数组中的
位置，若他们中的任何一个被dsicard了，就的扫描整个数组，找到新的Max和Min
value的，对吧？平均来说 amortized time可能还是O（1）。
或者用两个stack，分别装每个时刻的Max和Min value，Max和Min value被从12个月的
数组discard后就从stack pop掉。 |

Is it safe to save your breastmilk after offering to baby?
There has only been one small study of breastmilk that has been stored,

previously stored milk up to one or two hours after it has been prepared.
Any unused portion should then be discarded.
