MapReduce是一种编程模型，用于大规模数据集（大于1TB）的并行运算。概念"Map（映射）"和"Reduce（归约）"，是它们的主要思想，都是从函数式编程语言里借来的，还有从矢量编程语言里借来的特性。它极大地方便了编程人员在不会分布式并行编程的情况下，将自己的程序运行在分布式系统上。 当前的软件实现是指定一个Map（映射）函数，用来把一组键值对映射成一组新的键值对，指定并发的Reduce（归约）函数，用来保证所有映射的键值对中的每一个共享相同的键组。
MapReduce is a programming model for parallel computing of large data sets (greater than 1TB). The concepts "map" and "reduce" are their main ideas. They are borrowed from functional programming language and vector programming language. It greatly facilitates the programmers to run their own programs on the distributed system without distributed parallel programming. The current software implementation is to specify a map function, which is used to map a set of key value pairs into a new set of key value pairs, and specify a concurrent reduce function, which is used to ensure that each of the mapped key value pairs shares the same key group.

这个任务的目的是更熟悉位级表示和操作。你会通过解决一系列的编程难题来解决这个问题。“很多这样的谜题都是人为的，但你会发现的。你自己想的更多的是通过你的方式通过他们，你将学到很多关于如何计算机表示整型数据。
The purpose of this assignment is to become more familiar with bit-level representations and manipulations. You'll do this by solving a series of programming ``puzzles.'' Many of these puzzles are quite artificial, but you'll find yourself thinking much more about bits in working your way through them and you will learn a lot about how computers represent integer data.
