变量和相等问题的设计和实现将a、b、c、d、e、f这6个变量排成如图所示的 三角形，这6个变量分别取 1——6的整数，且均不相同。求使三角形三条边上的变量之和相等的全部解，如 3 6 2 1 4 5 为一个解。 程序引入变量a,b,c,d,e,f,并让它们分别取1——6的整数，在它们互不相等的 条件下， 测试由它们排成如图所示的三角形三条边上的变量之和是否相等，如相等即为一种满足要求的排列，把它们输出。当这些变量取尽所有的组合后，程序就可得到全部可能的解。

This document provides guidelines for integrating a discrete high speed USB host controller onto a fourlayer desktop motherboard. The material covered can be broken into three main categories: Board design guidelines, EMI/ESD guidelines and front panel USB guidelines. Section 1.1 Background provides an explanation of the routing experiments and testing performed to validate the feasibility of 480 Megabits per second on an actual motherboard. Section 7 contains a design checklist that lists each design recommendation described in this document. High speed USB operation is described in the USB 2.0 Specification (http://www.usb.org/developers/docs.html).

Universal Serial Bus (USB) is a communications architecture that gives a personal computer (PC) the ability to interconnect a variety of devices using a simple four- wire cable. The USB is actually a two-wire serial communication link that runs at either 1.5 or 12 megabits per second (mbs). USB protocols can configure devices at startup or when they are plugged in at run time. These devices are broken into various device classes. Each device class defines the common behavior and protocols for devices that serve similar functions. Some examples of USB device classes are shown in the following table
