int main(){
  int n,l;
  scanf("%d %d",&n,&l);

  char temp[101];
  char str[100][101];

  int i,j;
  for(i=0;i<n;i++){
    scanf("%s",&str[i]);
  }

  for(i=0;i<(n-1);i++){
    for(j=(n-1);j>i;j--){
      if(strcmp(str[j-1],str[j])>0){
        strcpy(temp,str[j-1]);
        strcpy(str[j-1],str[j]);
        strcpy(str[j],temp);
      }
    }
