Re: 10189 - Minesweeper
There must be an empty line between field outputs. Don't print an extra blank line at the end.
Check input and AC output for thousands of problems on uDebug!
Re: 10189 - Minesweeper
still returning Wrong Answer :/
@edit
It's not Presentation Error, but all the test cases worked

Re: 10189 - Minesweeper
Post your updated code.
Missing or extra newline chars will usually result in WA, not PE.

I am experiencing WA for this code
Could you please point out what kind of consideration is needed for this minesweeper case ?
Code: Select all
#include <stdio.h>
#define MAX_NUM 100
#define STAR 777
int answer[100][100];
int subset[8][2] = {
{-1, -1},
{-1, 0},
{-1, 1},
{0, -1},
{0, 1},
{1, -1},
{1, 0},
{1, 1}
};
int N, M;
void increase_adjacent_field(int n, int m)
{
int i;
int _n, _m;
for (i = 0; i < 8; i++) {
_n = n + subset[i][0];
_m = m + subset[i][1];
if (_n >= 0 && _n < N && _m >= 0 && _m < M)
if (answer[_n][_m] != STAR)
answer[_n][_m] += 1;
}
}
int main(void)
{
int i, j;
char ch;
int count = 1;
while (scanf("%d %d", &N, &M) != EOF) {
if (!N && !M)
break;
for (i = 0; i < N; i++) {
j = 0;
while(j < M) {
scanf("%c", &ch);
if (ch == '*')
answer[i][j++] = STAR;
else if (ch == '.')
answer[i][j++] = 0;
}
}
for (i = 0; i < N; i++)
for (j = 0; j < N; j++)
if (answer[i][j] == STAR)
increase_adjacent_field(i, j);
printf("Field #%d:\n", count);
for (i = 0; i < N; i++) {
for (j = 0; j < M; j++) {
if (answer[i][j] == STAR)
printf("*");
else
printf("%d", answer[i][j]);
}

Re: 10189 - Minesweeper
This is not the problem. Has an empty line between field outputs and doesn't has a blank line at the end.
Re: 10189 - Minesweeper
Hi i can't find what I am doing in my java code for this problem. I found out that it only works in eclipse where i enter the grid size then press enter then paste the fields then repeat again for all test cases. That is:
Here is my code :
Then press enter , then paste the rest :4 4
However if i paste a single test case all at the same time nothing happens , and if i do it on ideone i get run-time error.*...
....
.*..
....
Here is my code :
Code: Select all
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.StringTokenizer;
public class Main {
static int field=0;
public static void main(String [] args) throws IOException{
BufferedReader bf=new BufferedReader(new InputStreamReader(System.in));
StringTokenizer s=new StringTokenizer(bf.readLine());
int b=Integer.parseInt(s.nextToken()), a=Integer.parseInt(s.nextToken());
while(b!=0 && a!=0){
field++;
mine(b,a);
s=new StringTokenizer(bf.readLine());
b=Integer.parseInt(s.nextToken()); a=Integer.parseInt(s.nextToken());
}
}

*********************JAVA*********************
Same problem as many, code works, even with the critical input.
Like brianfry713 said to many others, there might be a newline missing or one too much but I cannot find it.
It seems right to the point. There should be no newline after '0' '0' input and there should be a newline between the input.
Hopefully someone could help me get this code accepted...
Thanks in advance.
Well nevermind, we found the problem and got accepted.
Like the rest it was a newline problem, which got solved with a simple if condition.
