Have a few questions .. (1) doesn't it seem like this only works for elements that have an ordering as well a binary operation multiplication, subtraction and addition defined on them, making it too specific ? (I'm talking about the whole 2x - minelement) (2) If I have a variable hanging around a stack, is it still a stack? (3) When I pop out the min value in the stack, and want the next min Value, how do I get that,? seems like the previous min value still sticks around? (4) With comparisons and 1 value that hols state, do I really need to transform the values going into the stack?
