胜一场得2分，输一场得1分，未出场比赛或未完成比赛的 场次为0分
名次计算分两步：
，根据所获得的场次分数多少决定。
2－①，如果有两个或更多的队得分相同，他们有关的名次应按他们相应之间比赛的成绩决定，首先计算他们之间获得的场次分数多少决。
2－②如果还相同，再根据他们相应之间比赛获胜局数和负的局数比率，算出名次。

我不是很清楚你说的分散（distribution）和解中位数（median）
数是怎么回事。我把结果排列出来。具体你看一下。
或者解释一下分散还有中位数的计算方式我再给你具体试试写下
int a[20];
int i=0;
int min,max;//最大值和最小值坐标
int all = 0;
while(i < 20)
{
scanf("%d",a[i++]);
}
min = 0;
max = 0;
for(i=0;i<20;i++)
{
if(a[i] <min)
{
min = i;
}
if(a[i] > max)
{
max = i;
}
}
//最大值 和最小值 清0
a[min] = 0;
a[max] = 0;
for(i=0;i<20;i++)
{
all += a[i];
}
printf("平均值 =%f",all/20);
