数据ms有误

Posted by tekkie at 2007-08-07 14:47:53 on Problem 3330
(((x ((x x) x)) (x x)) ((((x (x x)) (x x)) (x x)) (((x x) ((x x) (x x))) ((x x) ((x x) x)))))
这个是官方数据中输出部分截出的一段
应该是排好顺序的,但是我的结果是
(((((x (x x)) (x x)) (((x x) (x x)) (x x))) ((x x) ((x x) ((x x) x)))) ((x x) ((x (x x)) x)))
手工验证自己应该是对的,所以数据是不是有问题,请大家看看
(几百组数据,我就错这一组)
感觉是官方在精度处理上除了问题,在计算时直接给判断掉了
