这题是道三分的题,首先要分析满足条件的情况,这个就是平面几何的功夫了.要想车子能够转弯成功,最上面那个点到水平线的距离要小于等于y.这里h和s的公式就是利用平面几何的知识求出来的:s=l*cos(a)+w*sin(a)-x;s=l*cos(a)+w*sin(a)-x;其中s为最右边的那个点到拐角处的水平距离.因为角度和高度h满足凸函数的关系,因此想到利用角度采用三分的方法进行求解. #include"iostream" #include"stdio.h" #incl…

托一个学弟的福,学了一下他的最简便三分写法,然后找了一道三分的题验证了下,AC了一题,写法确实方便,还是我太弱了,漫漫AC路!各路大神,以后你们有啥好的简便写法可以在博客下方留个言或私信我,谢谢了! Turn the corner Time Limit: 3000/1000 MS (Java/Others)    Memory Limit: 32768/32768 K (Java/Others) Total Submission(s): 3196    Accepted Submission(s…
