this is my code, I'm using c++

Code: Select all

(removed)

I don't find anything wrong in my code, could someone give me an input to prove my code wrong?

Code: Select all

12
X XXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXX
0

The right result is 1 (obviously). Think: why does your solution output 24 for this case? =).

Please remove your code after reading this post so it doesn't spoil the fun to others.

thanks a lot, now I realize my mistake

my thought is to find the max num of the 'X', and do sub to find..And i have tested lots of cases..Maybe there is something wrong with my I/0..Help.!

Code: Select all

#include <iostream.h>
#include "string.h"

int main ()
{
	char str[13][26];
	int count[13];
	int row;
	int max;
	int i, j;

	while (cin>>row && row)
	{
		max = 0;
		for (i = 0; i < row; i++)
		{
			cin.get ();
			cin.getline (str[i], 26);	
		}

		for (i = 0; i < row; i++)
		{
			count[i] = 0;
			for (j = 0; str[i][j] != '\0'; j++)
				if (str[i][j] == 'X')
					count[i]++;

			if (count[i] > max)
				max = count[i];
		}

		j = 0;
		for (i = 0; i < row; i++)
			if (count[i] < max)
				j += max - count[i];

		cout<<j<<endl;
	}
	return 0;
}

Code: Select all

for (i = 0; i < row; i++)
      {
         gets (str[i]);   
      }

      for (i = 0; i < row; i++)
      {
         count[i] = 0;
         for (j = 0; str[i][j] != '\0'; j++)
            if (str[i][j] == 'X')
               count[i]++;

         if (count[i] > max)
            max = count[i];
      }

this code creates WA.
u can use

Code: Select all

while(1)
{
	scanf("%c",&c);
        check '\n'
	{
	    Array=count;
	    check min(count<max)
		     max=count;
		    break;
	}
	otherwise(c==' ')
		 count++;
}

hope it helps.
