1208 - Oreon

Post by draconian devil » Sat Jul 13, 2013 11:12 am

Getting Wrong Answer on UVA 1208 Oreon. Its a straight forward MST problem i think. dont know why i got WA

Code: Select all

#include <iostream>
#include <vector>
#include <cstring>
#include <algorithm>

#define N 55000
using namespace std;

int P[N];

class info
{
public:
	int p,c,guard;
};

bool compare(info i1, info i2)
{
	if(i1.guard == i2.guard)
		return i1.p < i2.p;
	return i1.guard<i2.guard;
}
int Union(int node)
{
	if(P[node] == node) return node;
	return P[node] = Union(P[node]);
}

bool makeUnion(int p, int c)
{
	if(Union(p) != Union(c))
	{
		P[p] = c;
		return true;
	}
	return false;
}
int main()
{	
	int testcase;
	cin >> testcase;
	for(int  t = 1 ; t <= testcase ; t++)
	{	
		int citynum;
		vector <info> city;
		cin >> citynum;

		for(int i = 0 ; i < citynum ; i++)
		{
			for(int j = 0; j < citynum ; j++)
			{
				info temp;
				char c;
				temp.p = i; temp.c = j; cin >> temp.guard;
				if(temp.guard!=0)
					city.push_back(temp);

				if(j < citynum-1)
					cin >> c;
			}
		}

		for(int  i = 0 ; i < citynum ; i++)
			P[i] = i;

		sort(city.begin(),city.end(),compare);

		vector <info> result;

		int a = city.size();
		for(int i = 0 ; i < a ; i++)
		{
			if(makeUnion(city[i].p,city[i].c))
			{
				result.push_back(city[i]);
			}
		}
		int b = result.size();
		cout << "Case " << t << ":" << endl;

		for(int i = 0 ; i < b ; i++)
		{
			char p,c;
			p = result[i].p + 65; c = result[i].c + 65;
			cout << p << "-" << c << " " << result[i].guard << endl;
		}
	}
}

Change line 33 to:
P[P[p]] = P[c];
