乒乓球竞赛 c++大作业-代写

方案A

2020年要举行新一年的乒乓球比赛了。今年比赛的选手总数（[8-16]）和选手名单（名字各不相同）在程序运行前通过命令行输入。请按照双败淘汰制随机列出一份初始比赛名单，每场比赛都是3局2胜制，每场比赛的结果在程序运行阶段输入。每轮比赛前，打印出两两对阵名单（相同败率的选手随机安排对局），比赛后要输入各场比赛的结果，然后打印出下轮比赛的名单，直到决出冠亚军为止。最后打印比赛前4名的名字。如果选手数量是单数，可能会轮空，轮空算晋级获胜处理。

程序执行如下：

$ ./game 8 Alice Bob Charlie Dave Ele Flemming Gorge Howard

以上紫色字体是命令行输入的字符串.

请按照题目要求自行设计数据类型和算法，要

求每次运行同样的数据输出的结果不一样。
