[rails-oceania] Re: Algorithm Problem

[Mark Ratjens]

without knowing PHP or your data structure ... can you build an array of arrays, option group x option? Recursive iteration through the arrays can work then Torm3nt wrote: Yeah variable number of option groups, currently working with PHP.

Either that or get some sleep :-) Torm3nt wrote: This may seem rather simple to some, but being late at night it's driving me up the wall.. The context behind this is I'm trying to create all unique product options for a product. Consider: We have two product option groups, size and colour. Size contains: S, M, L, XL Colour contains: red, blue, green, black, brown I need to write an algorithm (this isn't for ruby btw, so no ruby idioms =P), that gets all unique combinations, for example: S red, S blue, S green, S black, S brown M red, M blue.etc.etc. They're all valid, but I can't then go: red S - it's exactly the same option as before. I have tried to do this three different ways and each way I've hit a daed end.
