先要求出各个加油站 最短的 与任意一房屋之间的 距离D,再在这些加油站中选出最长的D的加油站 ,该加油站 为 最优选项 (坑爹啊!).如果相同D相同 则 选离各个房屋平均距离小的,如果还是 相同,则 选 编号小的. 时间限制 200 ms 内存限制 65536 kB 代码长度限制 16000 B 判题程序 Standard 作者 CHEN, Yue A gas station has to be built at such a location that the minimum distance…
A gas station has to be built at such a location that the minimum distance between the station and any of the residential housing is as far away as possible. 考试的时候这句话意思没有完全理解,悲剧鸟... 其实就是让你找一个加油站,它到所有房子最短距离为len , 找一个加油站len的距离越大越好 加油站最多10个,以这几个加油站为原点,做…

题意: 输入四个正整数N,M,K,D(N<=1000,M<=10,K<=10000)分别表示房屋个数,加油站个数,路径条数和加油站最远服务距离,接着输入K行每行包括一条路的两条边和距离.输出最近距离最远同时与所有房屋距离都不超过D的加油站名字和最近距离以及平均距离.如果有多个答案则优先输出平均距离最小的,再不唯一则输出编号最小的. trick: 这题有一个诡异的事情,样例1的平均距离是3.25,取一位小数应该是3.2,四舍五入则是3.3,样例显示为3.3,此时我理解为四舍五入,题面说是精…

题意:从m个加油站里面选取1个站点,使得其离住宅的最近距离mindis尽可能地远,并且离所有住宅的距离都在服务范围ds之内.如果有很多相同mindis的加油站,输出距所有住宅平均距离最小的那个.如果平均值还是一样,就输出按照顺序排列加油站编号最小的. 分析:加油站之间也是彼此有路连接的,所以最短路径计算的时候也要把加油站算上,是双向边,所以边的数组大小得开两倍.加油站编号记为n+1~n+m,对这些点用dijkstra计算最短路径即可,这里顺便在dijkstra中进行了剪枝处理,不剪枝也没事. #…

On a horizontal number line, we have gas stations at positions stations[0], stations[1], ..., stations[N-1], where N = stations.length. Now, we add K more gas stations so that D, the maximum distance between adjacent gas stations, is minimized. Retur…
