Subject: Tries are to sequences as ? is to trees
Date: Sat, 26 Apr 2008 02:20:04 +0100 [thread overview]
Message-ID: <200804260220.04921.jon@ffconsultancy.com> (raw)
So tries let us associate sequences with values. What data structure lets us
associate trees with values?
I ask because I am interested in replacing hash consing of expressions with a
purely functional equivalent so I need a way to map expressions onto
expressions.
The only idea I've come up with so far is to fold over the tree to make a
sequence and use that as the key into a trie but it seems a bit naff...
