Check for duplicates in array of size 50

[rtkriishna]

--------------------------------------------------------------------------------

Any way to check for duplicates in an array apart from looping with each element. if my array size is 50 that is almost 50 * 50 checks if I loop through..

please help.

How about sorta then read through and compare to previous element.
Won't be 50*50

Hi rtkriishna:

Not quite 50 * 50 but that's probably what you had in mind

 d     arr         s             20a   dim(6)      
 d     X           s              2S 0             
  /FREE                                            
      arr(1) = 'a';                                
      arr(2) = 'b';                                
      arr(3) = 'c';                                
      arr(4) = 'c';                                
      arr(5) = 'd';                                
      arr(6) = 'e';                                
       FOR X = 1 TO 5;                             
          IF  %LOOKUP(ARR(X):ARR:(X+1)) <> 0;        
               DSPLY (ARR(X) + ' ' + %CHAR(X));      
          ENDIF;                                     
       ENDFOR;                                     
     *inlr=*on;

But that is also similar to 50 * 50 --internally the operation does the same aint it,.,.

Why don't you check for duplicates when you load the array?

Then, when you load a new array element, you only need to check the array elements that have been loaded thus far to see if its a duplicat.

ie: if you only have 5 loaded array elements, then before you load the next array element, you can check elements 1 thru 5 to see if its a duplicate.

Hey Michael,

That was another valid point. Any data received can be validated. I receive the data from front end html page in arrays.
I validate their duplication by loadinginto another temp array after check with lookup.

It helped!!

IT Works!! - Krish
