坑爹到精度问题

Posted by lzqxh at 2012-04-04 23:00:46 on Problem 2976

AC的方法
		while ( fabs(g-h)>1e-2 )
		{
                        mid = (g+h)/2;
			if ( pan(mid)  ){
				g = mid; 
			}else h = mid; 
		}
		printf("%.0f\n" , mid );


WA的方法
		while ( fabs(g-h)>1e-2 )
		{
                        mid = (g+h)/2;
			if ( pan(mid)  ){
				g = mid; 
                                ans = mid; 
			}else h = mid; 
		}
		printf("%.0f\n" , ans );
明显第二个比第一个更接近精确值,但是确实WA。。。
强烈认为这些问题要special judge。。。不然比标程精确你就哭把
