为什么还是错的呢?高手指点一下!!!!!#include<stdio.h>
struct dat
{
int a;
int b;
};
int pan(struct dat *p1,struct dat *p2)
{
if((!((p1->a+p2->a)%2))&&(!((p1->a+p2->a)%2)))
{
p2->a=0;
p2->b=0;
return 1;
}
else
return 0;
}
int main()
{
struct dat a[10010];
int n,i,temp1,temp2,j;
while((scanf("%d",&n))!=EOF){
if(n==0)
{
printf("*\n");
return 1;
}
for(i=1;i<=n;i++)
{
scanf("%d%d",&temp1,&temp2);
if(temp1>temp2)
{
a[i].a=temp2;
a[i].b=temp1;
}
else
{
a[i].a=temp1;
a[i].b=temp2;
}
}
temp2=1;
for(i=1;i<=n;i++)
{
temp1=1;
if(a[i].a==0)continue;
for(j=i+1;j<=n;j++)
{
if(a[j].a==0)continue;
if(pan(&a[i],&a[j]))
temp1++;
}
if(temp1>temp2)
temp2=temp1;
}
printf("%d\n",temp2);
}
return 1;
}
