I am new on topcoder, i try to submit the following code for the second problem and i got compilation error, i wasted much time on that, so i decided implemented it on python, finally only remains 10 min and i got very low score on this problem. Someone can said me, why i got compilation error ?

class OrderlyString
{
public:
	int longestLength(string s)
	{
		int n = s.length();
		vector<vector<int> > dp(n+1, vector<int>(26, -100000000));
		dp[0][0] = 0;
		for (int i = 0; i < n; ++i)
			for (int j = 0; j < 26; ++j)
			{
				dp[i+1][j] = max(dp[i+1][j], dp[i][j]);
				if (j <= (s[i]-'A'))
					dp[i+1][s[i]-'A'] = max(dp[i+1][s[i]-'A'], dp[i][j]+1);
			}
		return *max_element(dp[n].begin(), dp[n].end());
	}
};

    Missing headers and using namespace std? Trying to compile for Java instead of C++? You have compilation errors listed when you try to compile, read them and figure it out from there.

      I added #include <bits/stdc++.h> using namespace std; and got CE again, i compiled in c++, but now i am not sure about this "You have compilation errors listed when you try to compile, read them and figure it out from there." Thanks for replied

        When you click Compile, a window pops up, either telling you "compiled successfully" or listing the compiler output. Focus on that compiler output. If it doesn't, that's your problem or an arena problem, it happens for me.

That 250 and 500 should've been reversed. 500 was very easy and 250 had some nice evil parts — no, making sure you don't divide by zero isn't enough! (Also, I hacked a solution that avoids division by zero in all cases except $$$w=w_1=1$$$ and/or $$$h=h_1=1$$$. You know, the first thing to customtest.)

    It is actually listed in the main statement at the start of the second paragraph: "The tomb is divided into as many as six chambers."

Seems like ratings were updated, but the results are still at "everyone failed 250". Any idea if it's going to stay like this?
