This is a problem in a programming contest but I am stuck at it for the past two days

Here is a link to the problem : http://www.techgig.com/codecontest_detail.php?type=advanced

```
void DrowningVillage(int gridSize,int villageHeights[][10],int origin[])
{
int i=0,j,k=0,x=origin[1],y=origin[0],z=0,output1[100],Heights[10][10];
for(i=0;i<gridSize+2;i++)
for(j=0;j<gridSize+2;j++)
Heights[i][j]=1000; //For removing garbage values and for later comparisons
for(i=0;i<gridSize;i++)
for(j=0;j<gridSize;j++)
Heights[i+1][j+1]=villageHeights[i][j]; //Converting matrix so garbage values do not fall in comparisons
for(i=0;i<100;i++)
output1[i]=1000;
for(j=1;j<=gridSize*gridSize;j++)
{
output1[k++]=Heights[x][y];
output1[k++]=Heights[x-1][y]; //Storing neighbors in output1 array and then comparing them
output1[k++]=Heights[x+1][y];
output1[k++]=Heights[x][y-1];
output1[k++]=Heights[x][y+1];
for(z=j;z<k;z++) //Finding the smallest number
if(output1[z]<=output1[j])
output1[j]=output1[z];
if(output1[j]==Heights[x][y+1]) //changing the origin to smallest number
{
y=y+1;
Heights[x][y-1]=1000;
}
else if(output1[j]==Heights[x][y-1])
{
y=y-1;
Heights[x][y+1]=1000;
}
else if(output1[j]==Heights[x+1][y])
{
x=x+1;
Heights[x-1][y]=100;
}
else if(output1[j]==Heights[x-1][y])
{
Heights[x][y+1]=100;
x=x-1;
}
}
for(i=0;i<gridSize*gridSize;i++)
cout<<output1[i];
}
```

I am getting correct output for the first two elements but after that it only shows the smallest number afterwards present in the array. It would be really helpful if anybody could tell me where is the problem or point me into the right direction .

P.S : I am just a student and I am not cheating or anything. I was just participating for solving puzzles and experience and I am just posting to get a different and probably more experienced perception.
