It would be a junction if the only question was "is it bigger than 21?"... but that is not the case, it looks more like... Given S as the set of possible sums, Given V as a subset of S where < 21 Given I as a subset of S where > 21 If V is empty, Define X as the minimum value of I Else, Define X as the maximum value in V Which really looks like set operations... daniel
