Finding all non-conflicting combinations of values from multiple lists of values

Question

I have the following array which contains arrays of values:

$array = array(
    array(\'1\', \'2\'),
    array(\'a\', \'b\', \'c\'),
    array(\'x\', \'y\'),         


        

Answer 1

probably not the most elegant way, but does the trick (javascript)

var result = [];

for(i=0;i
