Depth First Search - Won't compile

[jumper007]

Hi, I've been trying to implement this Depth First Search graph algorithm using STL, and I get some error from Visual C++ 2012 at compilation.

The code is:

#include <fstream>
#include <stack>
#include <vector>
#include <algorithm>

using namespace std;

#define Max 100
#define Fin fstream in("graph.in", ios::in)
#define Fout fstream out("graph.out", ios::out)

int adjacent[Max][Max];
int nodes;
stack<int> st;
vector<int> v;

void Read()
{
	Fin;
	in >> nodes;
	st.push(0);
	for(int i = 0; i <= nodes; ++i)
		for(int j = 0; j <= nodes; ++j)
			in >> adjacent[i][j];
}

void Compute()
{
	Fout;
	while(!st.empty())
	{
		int t = st.top();
		for(int i = nodes; i >= 0; --i)
		{
			if((adjacent[t][i] != 0) && (find(v.begin(),v.end(),i) == v.end()))
				st.push(i);
			if(find(v.begin(),v.end(),t) == v.end())
				v.push_back(t);
			else
				st.pop();
		}
	}
	for(int i = 0; i < v.size(); ++i)
		out << v[i]+1 << " ";
}

int main(int argc, char **argv)
{
	Read();
	Compute();
	system("pause");
	return 0;
}

And the error says something like this:

Debug Assertion Failed!

Program: C:\Windows\SYSTEM32\MSVCP110D.dll
File: d:\...\vs2012\vc\include\deque
Line: 1497

Expression: deque empty before pop

Any ideas about what might cause this problem ?

Never mind. Found the problem. Sorry for the post.
It was the extra brackets at lines 34 and 41 and the wrong comparison on lines 22 and 23 ( <= instead of < ).
