The balance was the first mass measuring instrument invented. In its traditional form, it consists of a pivoted horizontal lever of equal length arms, called the beam, with a weighing pan, also called scale, suspended from each arm (which is the orig…
Given an array of integers, return indices of the two numbers such that they add up to a specific target. You may assume that each input would have exactly one solution, and you may not use the same element twice. Example: Given nums = [2, 7, 11, 15]…
MapReduce编程模型 在Google的一篇重要的论文MapReduce: Simplified Data Processing on Large Clusters中提到,Google公司有大量的诸如Web请求日志.爬虫抓取的文档之类的数据需要处理,由于数据量巨大,只能将其分散在成百上千台机器上处理,如何处理并行计算.如何分发数据.如何处理错误,所有这些问题综合在一起,需要大量的代码处理,因此也使得原本简单的运算变得难以处理. 为了解决上述复杂的问题,Google设计一个新的抽象模型,使用这…
