PDF417二维条码是一种堆叠式二维条码，目前应用最为广泛。PDF417条码是由美国SYMBOL公司发明的， PDF（Portable Data File）意思是“便携数据文件”。组成条码的每一个条码字符由4个条和4个空共17个模块构成， 故称为PDF417条码。 PDF417条码需要有417解码功能的条码阅读器才能识别。PDF417条码最大的优势在于其 庞大的数据容量和极强的纠错能力。   

Tug of War(A tug of war is to be arranged at the local office picnic. For the tug of war, the picnickers must be divided into two teams. Each person must be on one team or the other the number of people on the two teams must not differ by more than 1 the total weight of the people on each team should be as nearly equal as possible. The first line of input contains n the number of people at the picnic. n lines follow. The first line gives the weight of person 1 the second the weight of person 2 and so on. Each weight is an integer between 1 and 450. There are at most 100 people at the picnic. Your output will be a single line containing 2 numbers: the total weight of the people on one team, and the total weight of the people on the other team. If these numbers differ, give the lesser first. )

It s a book of design patterns that describes simple and elegant solutions to specific problems in object-oriented software design. Design patterns capture solutions that have developed and evolved over time. Hence they aren t the designs people tend to generate initially. They reflect untold redesign and recoding as developers have struggled for greater reuse and flexibility in their software. Design patterns capture these solutions in a succinct and easily applied form.-Design_Patterns_Elements_Of_Reusable_Object_Oriented_Software
