consider there are categories and these have IDs like
below:
1, 2, 4, 8, 16, 32, 64...
if some data belongs to more than 1 category for
exemple 4 and 32, its category ID will be 36, the sum
of cat. IDs.
i guess this is used widely in programming. so, how
can i resolve the original IDs. i mean what kind of
script can tell me what+what1+what2...whatN = 79?
