题意:给你一串数,没个数只能往前提到首位,或则往后放末尾.问最少步骤使操作后的序列成上升序列. 思路:最长连续子序列. #include<iostream> #include<stdio.h> #include<stdlib.h> #include<memory.h> #include<string.h> #include<algorithm> #include<cmath> ; ; using namespace std…
求一下最长数字连续上升的子序列长度,n-长度就是答案 O(n)可以出解,dp[i]=dp[i-1]+1,然后找到dp数组最大的值. #include<cstdio> #include<cstring> #include<cmath> #include<algorithm> using namespace std; const int INF=0x7FFFFFFF; +; int dp[maxn]; int n,x; int main() { while(~s…
早起一水…… 题意看着和蓝桥杯B组的大题第二道貌似一个意思…… 不过还是有亮瞎双眼的超短代码…… 总的意思呢…… 就是最长增长子序列且增长差距为1的的…… 然后n-最大长度…… 这都怎么想的…… 希望今天的省选可以亮光乍现~~~ #include<stdio.h> #include<iostream> #include<string.h> #include<algorithm> #include<math.h> using namespace s…
