This problem has a bad dataset. My code checked if the safe place was at first a ‘free space’. The problem clearly specifies that only a free space can be safe to plant! But I got WA 
So I stopped checking if the place was free space and only checked if there was any * around the candidate spaces and voila! AC 
I think Toph should look into this 
@shantanu404 You are absolutely right.
The dataset has been updated and all submissions have been rejudged.
You’re welcome 
@shantanu404 I have already solved the problem.
However, I am interested in your code.
Can I get both of your codes? (after Updating TC and before)
Can you please Pastebin them to me?
It was super fun to solve this problem. 
Is it only who who is having issues with this problem.
I can’t point out my faults in the code and thus I need help.
here is my code:
length, breadth = map(int, input().split())
field = []
free_spots = 0
for i in range(length):
row = input()
field.append(row)
for i in field:
for j in i:
# for the middle ones
if length > field.index(i) >= 1 and breadth > i.index(j) >= 1:
if i[i.index(j) - 1] == ‘.’ and i[i.index(j) + 1] == ‘.’ and field[field.index(i) + 1][i.index(j)] == ‘.’ and field[field.index(i) - 1][i.index(j)] == ‘.’:
free_spots += 1
# for the top left corner
elif field.index(i) == 0 and i.index(j) == 0:
if i[i.index(j) + 1] == '.' and field[field.index(i) + 1][i.index(j)] == '.':
free_spots += 1
# for the bottom right corner
elif field.index(i) == length and i.index(j) == breadth:
if i[i.index(j) - 1] == '.' and field[field.index(i) - 1][i.index(j)] == '.':
free_spots += 1
# for the top right corner

if i[i.index(j) - 1] == '.' and field[field.index(i) + 1][i.index(j)] == '.':
free_spots += 1
# for the bottom left corner
if field.index(i) == length and i.index(j) == 0:
if i[i.index(j) + 1] == '.' and field[field.index(i) - 1][i.index(j)] == '.':
free_spots += 1
# for the top side
elif field.index(i) == 0 and breadth > i.index(j) >= 1:
if i[i.index(j) - 1] == '.' and i[i.index(j) + 1] == '.' and field[field.index(i) + 1][i.index(j)] == '.':
free_spots += 1
# for the bottom side
elif field.index(i) == length and 1 <= i.index(j) < breadth:
if i[i.index(j) - 1] == '.' and i[i.index(j) + 1] == '.' and field[field.index(i) - 1][i.index(j)] == '.':
free_spots += 1
# for the right side

free_spots += 1
print(free_spots)
Please format your code first using the method I specified here.
I am getting too many runtime errors.
You should check if your code runs properly before sharing to the community.
I know there is a problem with my code but I couldn’t pinpoint it. It’s showing index out of range in some problems thus making a runtime error. It would be a great help if you would hlp me figure out why I am getting index out of range.

please tell me the problem in this code . runtime error
What’s the problem with this code? It runs perfectly on my pc but here it is showing

Hey brother I try this problem many times But faild. Can you please give me the solution of this problem or find out the error of my code.
here is my code :
#include <stdio.h>
// #include <math.h>
#include <string.h>
// #include <stdlib.h>
int main()
{
int row, col, count = 0;
char ar[25][25];
scanf("%d %d", &row, &col);
for (int i = 0; i < row; i++)
{
for (int j = 0; j < col; j++)
{
scanf("%c", &ar[i][j]);
}
// getchar();
// printf("\n");
}
// for (int i = 0; i < row; i++)
// {
// for (int j = 0; j < col; j++)
// {
// printf("%c", &ar[i][j]);
// }
// // getchar();
// printf("\n");
// }
for (int i = 0; i < row; i++)
{
for (int j = 0; j < col; j++)
{
if (ar[i][j] == '.')
{
if ((ar[i + 1][j] != '*') && (ar[i - 1][j] != '*') && (ar[i][j + 1] != '*') && (ar[i][j - 1] != '*'))
{
count++;
// printf("row = %d \n coloum = %d = %c\n", i, j, ar[i][j+1]);
}
}
}
}
printf("%d\n", count);
return 0;
}
Facing issue with the logic
Well, So I have coded a little bit different and added free spaces in right, left, up and below… here is my main logic…
freeSpace = 0
for l in range(1, len(ground)):
for l1 in range(1, (len(ground2[l])-1)):
if ground2[l][l1] == ".":
if (ground2[l][l1-1] and ground2[l][l1+1] and ground2[l-1][l1] and ground2[l+1][l1]) == '.':
freeSpace += 1
else:
l1 += 1
Where the the lists is…
ground = [['.', '*', '*', '*', '*', '.', '.', '.'],['.', '*', '*', '*', '*', '*', '.', '.'],['.', '.', '.', '*', '.', '*', '*', '.'],['.', '.', '*', '.', '.', '.', '*', '.'],['.', '.', '*', '.', '*', '*', '.', '.'],['.', '.', '.', '*', '*', '.', '.', '.']]
ground2 = [['.', '.', '.', '.', '.', '.', '.', '.'],['.', '*', '*', '*', '*', '.', '.', '.'],['.', '*', '*', '*', '*', '*', '.', '.'],['.', '.', '.', '*', '.', '*', '*', '.'],['.', '.', '*', '.', '.', '.', '*', '.'],['.', '.', '*', '.', '*', '*', '.', '.'],['.', '.', '.', '*', '*', '.', '.', '.'],['.', '.', '.', '.', '.', '.', '.', '.']]
Full Code
x, y = 6, 6
ground = []
for i in range(x):
usr = input("")
ground.append(usr)
ground2 = []
# all list in for every abstract
for k in ground:
ground2.append(list(k))
ground2.insert(0, ['.', '.', '.', '.', '.', '.'])
ground2.insert((len(ground2)), ['.', '.', '.', '.', '.', '.'])
for o in range(len(ground2)):
ground2[o].insert(0, ".")
ground2[o].insert(len(ground2)+1, ".")
freeSpace = 0
for l in range(1, len(ground)):
for l1 in range(1, (len(ground2[l])-1)):
if ground2[l][l1] == ".":
if (ground2[l][l1-1] and ground2[l][l1+1] and ground2[l-1][l1] and ground2[l+1][l1]) == '.':
freeSpace += 1
else:
l1 += 1
print(freeSpace)
**Output comes 7 while the output could be 3 
**
