Given two rectangles, find if the given two rectangles overlap or not. A rectangle is denoted by providing the x and y co-ordinates of two points: the left top corner and the right bottom corner of the rectangle. Note that two rectangles sharing a si…

题意: 给定一个坐标系, 给出n个矩形的左下角坐标(bx,by)和右上角坐标(tx,ty) , 求矩形覆盖的面积, 有些区域会被多个矩形覆盖, 但只用算一次. n <= 1000,  0 <= bx,by,tx,ty <= 1e6 分析: 如果这题坐标范围很小的话, 其实可以直接开二维数组填充就好. 但因为坐标太大,无法开这样的数组,而且矩形数量不多,如果开这么大的数组很可能造成浪费,所以我们可以考虑离散化去做这题. 我觉得离散化的核心就是——用点去表示线段. 我们可以将n个矩形的2n个…

一,布局 R绘图所占的区域,被分成两大部分,一是外围边距,一是绘图区域. 外围边距可使用par()函数中的oma来进行设置.比如oma=c(4,3,2,1),就是指外围边距分别为下边距:4行,左边距3行,上边距2行,右边距1行.很明显这个设置顺序是从x轴开始顺时针方向.这里的行是指可以显示1行普通字体.所以当我们使用mtext中的line参数时,设置的大小就应该是[0,行数)的开区间.当我们使用mtext在外围边距上书写内容时,设置mtext中的outer=TRUE即可. 绘图区域可使用par(…

当内部网络也使用公网注册地址(或者是外网合法地址)时,如果仍使用标准的静态或者动态NAT转换,则可能使得转换的内网地址与外网中合法地址冲突,使数据包又返回到了本地网络,这肯定是不行的.这时我们就要使用重叠网络(Overlapping Network)的NAT转换方案了,把数据包中的目的地址转换成与外网不在同一网段的全局地址. 使用重叠(Overlapping)NAT可以实现内.外部网络都使用注册IP地址情况下的地址转换.这里的"重叠"其实就是指内.外部网络使用的IP地址段重叠(因为都是…
