D2D不仅可以绘制,还可以对多个几何图形对象进行空间运算.这功能应该在GIS界比较吃香. 这些计算包括: 合并几何对象,可以设置求交还是求并,CombineWithGeometry 边界,加宽边界,查询边界.Widen.GetBounds.GetWidenedBounds 几何对象填充的区域是否包含指定点,FillContainsPoint 笔画是否包含点,StrokeContainsPoint 几何对象与指定几何对象之间的交集,CompareWithGeometry 创建仅包含直线和(可选)三…

然而AK失败了,就是因为这道摸你题:(最后一篇题解了吧?QAQ) Solution 模拟多项式乘法,其中的运算处理很像高精度,不过第$i$位代表的就是$x^i$前面的系数了. 好像去年的时候就讲了表达式的计算(又开始玻璃心了QAQ),开双栈,一个栈表示数字,一个栈表示运算符.然后碰到右括号或者运算级低就弹栈.这里只是把数字的栈变成了多项式的栈而已QAQ 然后该怎么搞就怎么搞,虽然下面的代码并没有处理符号前驱的问题,然而数据中没有出. 作为纪念的摸你题了QAQ Code #include<bits…

题目链接:http://codeforces.com/problemset/problem/793/C 题目大意:给你一个捕鼠器坐标,和各个老鼠的的坐标以及相应坐标的移动速度,问你是否存在一个时间点可以关闭捕鼠器抓住所有的老鼠,误差不能超过1e-6. 解题思路:可以把每个老鼠进入捕鼠器的时间和出捕鼠器的时间计算出来,那就可以把一只进出捕鼠器时间当成一个集合,把各个集合求交集得到的就是最后可以捕到所有老鼠的时间范围,再取交集左边界时间就可以了. 千万要注意一点:老鼠不能在边界上被捕捉,表示之前没看…

引言 数学计算的模拟类题目,往往是要求实现某种计算(比如两数相除),实现的过程中会有所限定,比如不允许乘法等等. 这类题目首先要注意计算过程中本身的特殊情况.比如求相除,则必须首先反映过来除数不能为0. 其次要记得考虑负数的情况,如果计算范围不单单是整数,还要考虑double的比较方式. 最后要注意越界情况,这个是最容易犯错的,只能具体问题具体分析. 例题 1 不用"+ - * / "做加法 这道题来自于剑指Offer,为了归类,我把它放到了这里. 面试题 47(*),不用加减乘除做加…
