短小精悍贴个代码,都可以推导的大量?运算可能可读性不好

Posted by bellxtq at 2013-10-19 20:46:21 on Problem 1657
x,y分别代表x,y轴差值

王是x,y中最大值,后是x!=y?1:2,特别注意x==0&&y==0的时候是0,车是x==0||y==0?1:2也是在x&&y==0时是0
最后象稍复杂,观察图不难发现当x,y同奇偶(这时起点终点同色)的时候可到达,不然就是Inf
于是可到达情况下容易得出x==y?1:2

除了王以外其他人跑遍图不超过2步(除了到不了)


#include <stdio.h>

int main()
{
	int N;
	char a,c;
	int b,d,x,y;
	scanf("%d",&N);
	getchar();
	while(N--)
	{
		scanf("%c%d %c%d",&a,&b,&c,&d);
		getchar();
		x=a-c>0?a-c:c-a;
		y=b-d>0?b-d:d-b;
		printf("%d %d %d ",x>y?x:y,x==0&&y==0?0:(x==0||y==0?1:(x!=y?2:1)),x==0&&y==0?0:((x==0||y==0)?1:2));
		if((x&1)==(y&1))
		{
			printf("%d\n",x==0&&y==0?0:(x==y?1:2));
		}
		else
		{
			puts("Inf");
		}
	}


}
