In any case where there is no coin whose value, when added to the lowest denomination, is lower than twice that of the denomination immediately less than it, the greedy algorithm works. i.e. {1,2,3} works because [1,3] and [2,2] add to the same value however {1, 15, 25} doesn't work because (for the change 30) 15+15>25+1. professional website redesign services
