你切题太快了,都上700了。。。orz........In Reply To:不怕X一样的算法,就怕X一样的题意 Posted by:cangratul at 2009-09-18 17:04:00 > 一下是一些很重要的题意以及(自己猜测的)对应,你能发现多少?(序号表示优先级) > > 1.任何一次转弯都是前一次状态结束后下一个路口发生(包括起点),即其实你已经在你当前位置的(面朝的方向)前面一点点的地方了 > 对应:Position can be specified in terms of the last intersection you passed through (the numbers of the Avenue and Street that meet there) and your current heading > > 2.整个地图是100×100,那么”田“字所在的线和2条对角线是throughways.和题目给的图不是一回事 > 对应:the outer throughways will be labelled Fifty and the major and minor boulevards will cross at roads labelled Twentyfive. > > 3.是否在throughways上是由坐标和朝向共同决定的 > > 4.所有a circle的地方任何转向都是合理的 > 对应:however they always intersect each other at a circle, which is shared by all other roads that meet at that intersection.(什么,你问我和这个有什么关系?这个你应该去问神,我认为) > > 5.水平和竖直的throughways-只能以-left的形式来进或出,斜的throughways-只能以-sharpleft的形式来进或出 > 对应:You may only enter or leave them by turning left (sharp left in the case of boulevards). (这个说得通) > > 6.斜线上只能45,135,竖直‘水平的只能90,180,但有个地方是都可以的,那就是the major and minor boulevards的交点(25,25),(-25,25),(-25,25),(-25,-25) > > 7.S0,A0这2条分别对应 S0N ,A0E > 对应:If either of the roads involved is one of the central roads (A0, S0), they will be labelled N or E as appropriate. > > > 有了一上这些信息以后,剩下的就没什么好说的了··· > > 昨天做梦的时候,俨然梦见这道题这样对我说: > “爷考得不是算法,是阅读水平” Followed by:
