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

integer ListXneqY(list lx, list ly)
{
    if(lx == ly)
        return !(ListXnotY(lx,ly) == []);
    return TRUE;
}

Example:

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.
   }
}
