How can I know the number of all the possible parse trees?Hello!!! I have to make all the possible parse trees for the word But how can I know how many possible parse trees there are?Is there a formula with which I can find the number of all the possible parse trees? #2 20140127 07:00:06
Re: How can I know the number of all the possible parse trees?I think there are 6 of them here, since the difference between the trees will be in which order do you go through the operations (that is, those elements that correspond to P). You can go +*,*+,+*,+*,*+ or *+. The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #3 20140127 09:58:38
