(数学题)
高中数学学得还凑合,但是开始就猜的心态必须要制止,开始就猜就过分了,以后还是必须有理论证明再去写。西安留下了阴影,是我功利心太强。想要数据的可以拿走下面的测试数据转化为线性的来做,-r1到r1是圆心的范围。R到R是全集#include#include#include#include#includeusingnamespacestd;structnode{inti;doublex,y,l,val;}
但求-_-心安

题意:“吃鸡”,在一个半径为R的大圈里会随机的刷出半径为r的安全区,给n个建筑物,要求输出安全率最高的建筑的编号思路:考虑R跟r的关系,如果2*r>R,那么以大圈圆心为圆心的2*r-R范围内的建筑的安全概率是相等的应当是100%;如果2*r<R,那么以大圈圆心为圆心的R-2*r范围内的建筑的安全概率是相等的,因为以这个建筑物为圆心所画的半径为r的可覆盖此建筑的刷新范围完全在半径为R-2*r的这个圆

[LeetCode] Shortest Distance from All

之前听朋友说LeetCode出了一道新题,但是一直在TLE,我就找时间做了一下。这题是一个比较典型的BFS的题目,自己匆忙写了一个答案,没有考虑优化的问题,应该是有更好的解法的。基本想法就是从每个数值为1的点做bfs,遇到为0的点就加上相应的距离。这题因为要求到所有1的距离和最小的点,所以就可以无脑iterateover所有数值为1的点,并开一个二维数组来记录各个点的累加距离值。最后要检查一下所有

让上面的w和s都尽可能小,即w+s升序排序,值小的放在上面。这样一来,不管是w很大s很小或者s很大w很小,都可以使得最大的PDV尽可能地小,可以用笔写写看。 #include <stdio.h> #include <string.h> #include <stdlib.h> #include <algorithm> using names
