      int sum[101];
      int i,j,k,m,n,t;
      
      scanf("%d%d",&n,&m);
      for(i=0;i<m;i++)
       scanf("%s",&str[i]);
      
      for(i=0;i<m;i++)
        sum[i]=0;
     for(i=0;i<m;i++)    
      {for(j=0;j<n-1;j++)
        {for(k=j+1;k<n;k++)
            if(str[i][j]>str[i][k])
                sum[i]++;
        }
      }
 
     for(i=0;i<m-1;i++)
    {   for(j=i+1;j<m;j++)

            {    strcpy(temp,str[i]);
                 strcpy(str[i],str[j]);
			     strcpy(str[j],temp);
			      t=sum[i];
			      sum[i]=sum[j];
