求助！！POJ 1251 Runtime Error
各位路过走过的大神们，小弟最近在poj上练习，无奈总是遭遇Runtime Error，有些改改ac了，不过更多的是re···
我用的是VC，因为编程经验不足，所以很多错误不能发现，在这里请帮帮忙，看看下面的代码哪里出错了~
（ps：这题我采用的是prim算法求最小生成树，因为功夫不好，代码难看了点，各位将就啦~~）

Description



The Head Elder of the tropical island of Lagrishan has a problem. A burst of foreign aid money was spent on extra roads between villages some years ago. But the jungle overtakes roads relentlessly, so the large road network is too expensive to maintain. The Council of Elders must choose to stop maintaining some roads. The map above on the left shows all the roads in use now and the cost in aacms per month to maintain them. Of course there needs to be some way to get between all the villages on maintained roads, even if the route is not as short as before. The Chief Elder would like to tell the Council of Elders what would be the smallest amount they could spend in aacms per month to maintain roads that would connect all the villages. The villages are labeled A through I in the maps above. The map on the right shows the roads that could be maintained most cheaply, for 216 aacms per month. Your task is to write a program that will solve such problems.

Input

The input consists of one to 100 data sets, followed by a final line containing only 0. Each data set starts with a line containing only a number n, which is the number of villages, 1 < n < 27, and the villages are labeled with the first n letters of the alphabet, capitalized. Each data set is completed with n-1 lines that start with village labels in alphabetical order. There is no line for the last village. Each line for a village starts with the village label followed by a number, k, of roads from this village to villages with labels later in the alphabet. If k is greater than 0, the line continues with data for each of the k roads. The data for each road is the village label for the other end of the road followed by the monthly maintenance cost in aacms for the road. Maintenance costs will be positive integers less than 100. All data fields in the row are separated by single blanks. The road network will always allow travel between all the villages. The network will never have more than 75 roads. No village will have more than 15 roads going to other villages (before or after in the alphabet). In the sample input below, the first data set goes with the map above.
Output

The output is one integer per line for each data set: the minimum cost in aacms per month to maintain a road system that connect all the villages. Caution: A brute force solution that examines every possible set of roads will not finish within the one minute time limit.

我的代码：


#include "stdio.h"
#define INFINITY 1073741824
#define SIZE 300

int adjMatrix[SIZE][SIZE];

int isInTree(int intree[],int target)
{
int flag = 0;
int i;
for(i = 1;i<=intree[0];i++)
if(intree[i] == target)
{
flag = 1;
break;
}
return flag;
}

int LeastCostTree(int boundary)
{
int i,j,minj;
int minWeight,totalWeight = 0;
int inTree[SIZE] = {0};
inTree[1] = 0;
inTree[0] = 1;
while(inTree[0] < boundary)
{
minWeight = INFINITY;
minj = 0;
for(i=0;i<boundary;i++)
for(j=0;j<boundary;j++)
{
if(isInTree(inTree,i) && !isInTree(inTree,j) && minWeight>adjMatrix[i][j])
{
minWeight = adjMatrix[i][j];
minj = j;
}

}
totalWeight += minWeight;
inTree[0]+=1;
inTree[inTree[0]] = minj;
}

return totalWeight;
}

int main()
{
int weight = 0,wayNumber = 0;
int i,j,k;
int vertexNumber = 0;
char village = 0,target = 0;
while(1)
{
vertexNumber = 0;
scanf("%d",&vertexNumber);
if(!vertexNumber) break;
getchar();
for(i = 0;i<vertexNumber;i++)
for(j = 0;j<vertexNumber;j++)
adjMatrix[i][j] = INFINITY;
for(i = 0;i<vertexNumber-1;i++)
{
scanf("%c%d",& village,& wayNumber);
getchar();
for(k = 0;k<wayNumber;k++)
{
scanf("%c%d",&target,&weight);
getchar();
adjMatrix[(village-'A')][(target-'A')] = weight;
adjMatrix[(target-'A')][(village-'A')] = weight;
}
}
printf("%d\n",LeastCostTree(vertexNumber));
}

return 1;
}
