double length,wide,x0,y0,x1,y1;

int i;

char towards[1500];

while(1)

memset(towards,0,sizeof(towards));

if(scanf("%lf %lf",&wide,&length)==EOF)

break;

scanf("%lf %lf",&x0,&y0);

scanf("%lf %lf",&x1,&y1);

scanf("%s",towards);

for(i=0;i

{

if(towards[i]=='F')

y0=-y0;

if(towards[i]=='B')

y0=2*length-y0;

if(towards[i]=='L')

x0=-x0;

if(towards[i]=='R')

x0=2*wide-x0;

}

printf("%.4lf\n",sqrt((x0-x1)*(x0-x1)+(y0-y1)*(y0-y1)));

}

return(0);

}这是代码，如果学校需要相似度检测系统的话，建议看懂了自己写一下，不然被扣分了我可没有责任~~
