先上大佬写的代码。

    else{

      else{

下面是自己写的代码，有几个点运行超时，很无奈。

    int id;
    int de;
    int cai;

    scanf("%d %d %d",&n,&min,&max);

    for (i=0;i"%d %d %d",&a[i].id,&a[i].de,&a[i].cai);
        if (a[i].de>=min&&a[i].cai>=min)
        count++;
    }
    printf("%d\n",count);
    //第一类
    for (i=0;iif (a[i].de>=max&&a[i].cai>=max)
        b[0][x[0]++]=a[i];
    }
    //第二类
    for (i=0;iif (a[i].de>=max&&a[i].cai>=min&&a[i].cai<max)

    }

                }
            }
        }
