Summary

Function: integer ListCompare( list a, list b );

Efficiently compares two lists for equality (same contents).
Returns an integer TRUE if the lists are equal, FALSE if not.

• list a – The first list to compare.
• list b – The second list to compare.

Examples

integer r = ListCompare([1, 2.0, "3"], [1, 2.0, "3"]); // Returns TRUE
integer s = ListCompare([1, 2.0, 3], [1, 2.0, "3"]);   // Returns FALSE
integer t = ListCompare([], [1, 2.0, "3"]);            // Returns FALSE

Deep Notes

Implementation 

integer ListCompare(list a, list b) {
    integer aL = a != [];
    if (aL != (b != [])) return 0;
    if (aL == 0)         return 1;
 
    return !llListFindList((a = []) + a, (b = []) + b);
}
