D - Longest Subsequence 思路:枚举lcm, 每个lcm的答案只能由他的因子获得,类似素数筛搞一下. #include<bits/stdc++.h> #define LL long long #define fi first #define se second #define mk make_pair #define pii pair<int,int> #define piii pair<int, pair<int,int> > usi…

D. Longest Subsequence 题目连接: http://www.codeforces.com/contest/632/problem/D Description You are given array a with n elements and the number m. Consider some subsequence of a and the value of least common multiple (LCM) of its elements. Denote LCM a…
[徐州网络赛]Longest subsequence 可以分成两个部分,前面相同,然后下一个字符比对应位置上的大. 枚举这个位置 用序列自动机进行s字符串的下标转移 注意最后一个字符 #include <bits/stdc++.h> const int maxn = 1e6 + 7; using namespace std; #define ll long long int n, m; char s[maxn], t[maxn]; int nex[maxn][27]; void init()…
You are given array a with n elements and the number m. Consider some subsequence of a and the value of least common multiple (LCM) of its elements. Denote LCM as l. Find any longest subsequence of a with the value l ≤ m. A subsequence of a is an arr…
