参加运动会的n个学校编号为l～n。比赛分成m个男子项目和w个女子项目， 项目编号分别为l～m和m＋1～m＋w。由于各项目参加人数差别较大，有些项目 取前五名，得分顺序为7，5，3，2，1；还有些项目只取前三名，得分顺序为5， 3，2。设计一个统计系统按名次产生各种成绩单、得分报表。 -To participate in the Games n school numbered l ~ n. Competition is divided into m men and a woman w projects numbered l ~ m and m 1 ~ m w. As a result of differences in the number of participants larger projects, some projects from the top five scores in order of 7,5,3,2,1 also some of the items, only the top three scores in order of 5,3,2. Design a statistical system rankings produced by a variety of report card, scoring statements.

GRUB是计算机启动后运行的第一个软件，它负责加载一个操作系统的内核，并把控制权交给内核。该文档对GRUB进行了详尽的介绍，是一篇很不错的技术文档-GRUB after commencement of computers running the software, which is responsible for loading an operating system kernel. and control to the kernel. The right GRUB documentation for a detailed explanation, is a very good technical documentation
