I can't implement the State-space tree. How to implement it for subset sum problem?
What's the complexity of this?
Thanks in advance.

I have learned LIS with DP from MAXImal.But can not print the sequence. it just shows the longest length. if I want to print the sequence then what the modifies should I do.
http://e-maxx.ru/algo/longest_increasing_subseq_log
Here the code.
int main() { int n;
cin>>n; int dp[n+1],arr[n]; dp[0] = -INF; for(int i=0;i<n;i++){ scanf("%d",&arr[i]); dp[i+1]=INF; } for(int i=0;i<n;i++){ int j=upper_bound(dp,dp+n+1,arr[i])-dp; if(dp[j-1] < arr[i] && arr[i] < dp[j]) dp[j] = arr[i]; } for(int i: dp) cout<<i<<endl; return 0;
}
Sorry for my poor English.
