P1003 [NOIP2011 提高组] 铺地毯

第一思路: 开一个N*N的数组,每次都扫一遍地毯范围并标记编号 然后你会发现:喜提MLE 为什么呢? 我们来看看数据范围 0 ≤ n ≤ 1e4 n的范围是1e4,数组总大小为1e16,大约需要4000TB的内存空间 服务器也不带这么玩的 正解: 将地毯信息用结构体存储 struct node{ i ......

原题链接 解题思路 如果直接按照题意开一个二维数组来模拟每个点最上面的地毯编号,会发现所占空间最坏情况下约为 (2*105)2*4B=4*1010*4B=1.6*1011B≈149GB,程序完全无法运行。 但实际上没有必要将每一个点的信息记录下来,只需要记录每一块地毯能覆盖哪些点,再依次判断哪那些地 ......
