题意: n个数(1~n)取出r个数,取出的数相差要>=k, 然后分成m个可空组,问有多少种情况. 解法: 先看从n个数中取r个相差>=k的数的方法数,可以发现 dp[i][j] = dp[1][j-1] + dp[2][j-1] + ... + dp[i-k][j-1],(dp[i][1] = i)  即维护一个前缀和即可,可以在O(r*n)内得出. 然后n个不同的数分成m个可以空的组,即为第二类Strling数的和 : S[n][1] + S[n][2] + ... + S[n][m]. S…

传送门 题意: 从\(n\)个人中选\(r\)个出来,但每两个人的标号不能少于\(k\). 再将\(r\)个人分为不超过\(m\)个集合. 问有多少种方案. 思路: 直接\(dp\)预处理出从\(n\)个人选\(r\)个的方案,第二类斯特拉数处理分组的情况即可. /* * Author: heyuhhh * Created Time: 2019/12/10 19:14:48 * dp预处理+第二类斯特林数 */ #include <iostream> #include <algorith…
