试验内容： 跳水比赛中运动员每完成一个跳水动作，都有J名裁判员为其打分，但每次总成绩中都要去掉一个最高分和一个最低分。每个运动员需要完成C个动作，每次动作结束都要按当前总成绩为全部运动员重新排序，结果在运动员出场比赛时显示出来。设总共有N个运动员参加比赛，其编号为1，2，… N。 编一个程序实现这一功能。 要求： 1、　　建立一个*head为头结点的单链表 2、　　以动作C为主循环，对每个动作输入每个运动员所有裁判打分。输入每个 运动员的所有打分后，立即对单链表按sum域(累计分)从小到大重新排序 3、　　在每个动作之后，输出该单链表的所有结点-Note:

Experimentation:

When sportsman who taking part in diving game had finished each movement,there were J referees marking for sportsman,and each time the highest and lowest marks always were taken out.

Each sportsman must finish C movements,no sooner did actions had be performed than current sum grades should be sorted and the final results should be displayed before athlete comes out.

Supposing there are N athletes attending the game,the NO is 1,2,...N.Write an program to implement this fuction.

Requires:

1 Create a single chain naming the name of headnode*head.

2 The movement C is main loop,Each sportsman s grades marked by all judges should be put in the each movement.After finished this,the grades were immediately sorted from low to high by sum field in the chain.

3 After each action, all of node of the single chain must be oputed out.
