Question

making it faster and faster? how?

Asked by: kinghalls

So I am asked to do a simple task.. I have two file which contains a list of words.. the list of words is extremely huge and one is sorted and one is not.. I have to produce a third file which is the list of words that exists in both files and that produced list must be sorted in alphabetically.. right now the implementation is to sort those files in a linked list which is sorted.. and as we all know  this is really really bad..

Here's some of the info, the list of file or we can call it dictionaries as it is a dictionary:

I was thinking of storing both of these files first into a hash table and then compare two similar words and put them in a new output if they are similar..

is there any faster alternative?

/* Construct a dictionary of words.  When you create it, you may request
** the dictionary keep the dictionary in sorted order (or not) for
** iteration **/
typedef enum { UNSORTED_ORDER, SORTED_ORDER } sorted_e;
Words* DictionaryConstruct (sorted_e sorted);
 
 
 
Words* DictionaryConstruct (sorted_e sorted)
{
  /* TODO:  Don't use the the sorted_e ... should we ?  Right now
  ** we always keep everything sorted, but we can make things
  ** faster if we don't have to keep them sorted... */
  if (sorted==UNSORTED_ORDER) {
    /* ?? */
  } 
 
  Words* dummy = (Words*) malloc(sizeof(Words));
  dummy->next = 0;
  dummy->word = 0;
  dummy->count = -1;  /* Value to show we are at dummy node */
  return dummy;
}
