经典动态规划题,好!由此题虽然知道用动态规划但有时找状态方程没有那么容易,这也是动态规划中的难点。
今天做了三道经典的动态规划,感觉对动态规划有了更深的理解,但对状态转化方程还、
不太熟,还要努力!!
#include"iostream"
using namespace std;
int num[1001];
int f[1001];
int longest=1;
int main()
{
int n;
int max;
int i,j,k;
cin>>n;
for(i=0;i<n;i++)
cin>>num[i];
for(j=1;j<n;j++)
{
max=1;
f[0]=1;
for(k=0;k<j;k++)
{
if(num[k]<num[j])
if(f[k]+1>max)
max=f[k]+1;
}
f[j]=max;
if(max>longest)
longest=max;
}
cout<<longest<<endl;
return 1;
}
