ListXneqY

Function: integer ListXneqY(list lx, list ly);

Answers the question: is list X different from list Y?

Returns the number 1 if true, 0 if false

Note: requires also the function ListXnotY .

The opposite function is ListXequY .

See also: Lists

<lsl> integer ListXneqY(list lx, list ly) {

   if(lx == ly)
       return !(ListXnotY(lx,ly) == []);
   return TRUE;

} </lsl>

Example:

<lsl> list l1 = ["a","b","c","d", 1,2]; list l2 = ["a",1,"b",2,"c",3,"d"];

integer ListXneqY(list lx, list ly) {

   if(lx == ly)
       return !(ListXnotY(lx,ly) == []);
   return FALSE;

}

list ListXnotY(list lx, list ly) {// return elements in X list that are not in Y list

   list lz;
   integer n = llGetListLength(lx);
   while(n--)

if ( !~llListFindList(ly,llList2List(lx,n,n)) ) lz += llList2List(lx,n,n);

   return lz;

}

default{

  state_entry() {
     llSay(0, "Are we different lists? " + (string)ListXneqY(l1,l2));
     //will say in this example: 1 , meaning yes.
  }

} </lsl>
