 +====Generating all Trees==== 
 + 
 +"(Pruning and grafting.) Representing binary trees as in Algorithm B, design an algorithm that visits all link tables l1...ln and r1...rn in such a way that, between visits, exactly one link changes from j to 0 and another from 0 to j, for some index j. (In other words, every step removes some subtree j from the binary tree and places it elsewhere, preserving preorder)."
