待修改 nyoj 412 又是一个遗留问题

测试的数据都正确啊,跟别人正确代码也对比了一下,一直wrong ans,这道题是搞不定了,思路是这样的,一个int 的数, 例如一个数的二进制是1001100,那么大于这个数的最小的有相同个数1的数是都少? 我的思路是这样:既然最小那么我就每次加一试试:,然后判断1个数是否相同,以上个数为例. 10011_01 10011_10 10011_11 到此为止,1的个数一直在增加添加多少1呢? 添加在哪里呢? 10100—00 中1的位置,到 1001100中1的位置.为 5-3-1=…

SRM 627 D1L2GraphInversionsDFS查找指定长度的所有路径 Binary indexed tree (BIT)

题目:http://community.topcoder.com/stat?c=problem_statement&pm=13275&rd=16008 由于图中边数不多,选择DFS遍历全部路径,计算路径Inversions时使用了一个R[] 数组,能够在O(N)时间内得到路径Inversions,又由于该图所以路径条数为O(N^2),算法复杂度为O(N^3),对于N为1000的限制来说,复杂度较高,但实际測试中,最慢的測试用例费时700多ms,没有超时.若要减小复杂度,须要更高效的算法来计…

黑科技--位集--bitset

自从上次网赛发现这么个东西之后,深深地感受到了bitset的强大,0.0. 正常的bool占用1字节空间,bitset可以把这个缩到1bit,空间上8倍优化.正常用起来可能会跟位运算状态压缩类似,但是其中的每个位又能进行单独操作,所以确实相当方便. 下面是原版的文档: class template <bitset> std::bitset template <size_t N> class bitset; Bitset Abtsetstores bits (elements w…
