两个问题真心没有考虑到

Posted by liyue2011 at 2011-09-11 17:53:28 on Problem 1657
#include <stdio.h>
#include <math.h>

void distance(int x,int y,int a,int b)
{
    int king,queen,knight, chancellor;
    king=x>y?y:x+(int)fabs(x-y);
    if(x==y||x==0||y==0)
    {   
       queen=1;
       if(x==0||y==0)
          knight=1;
       else
          knight=2;
    }
    else
       queen=2;
    if((a%2==0&&b%2==0)||(a%2!=0&&b%2!=0))
    {  
        if(x==y)
           chancellor=1;
        else
           chancellor=2;
    }
    else
       chancellor=0;
    printf("%d %d %d ",king,queen,knight);
    if(chancellor==0)
       printf("Inf\n");
    else
       printf("%d\n",chancellor);
}
 
int main()
{
    int t,x,y,i,a,b;
    char spot1[5],spot2[5];//坑爹呀!!为毛把数组空间改为2就不能正常读入spot1的首位??? 
    scanf("%d",&t);
    for(i=0;i<t;i++)
    {
        scanf("%s %s",spot1,spot2);
        x=fabs(spot1[0]-spot2[0]);
        y=fabs(spot1[1]-spot2[1]);
        a=fabs(spot1[0]-spot1[1]);
        b=fabs(spot2[0]-spot2[1]);
        if(x!=0||y!=0)     //真心没有考虑到起始位置和末位置是同一个点 
           distance(x,y,a,b);
        else
           printf("0 0 0 0\n");
    }
    system("pause");
}
