为什么我的也是WA么??#include <iostream>
//#include <fstream>
using namespace std;
//ifstream fin("a.txt");
int solve(int );
int main()
{
int n;
cin>>n;
cout<<solve(n)<<endl;
return 1;
}
int solve(int n)
{
int i,j,max;
int num[1010];
int ans[1010];
for(i=0;i<n;i++){
cin>>num[i];
ans[i]=1;
}
for(i=n-2;i>=0;i--){
max=1;
for(j=i+1;j<=n-1;j++)
if(num[i]<num[j]&&max<ans[j]+1)
max=ans[j]+1;
ans[i]=max;
}
return ans[0];
}
