I'm looking for an elegant way to generate a list of all pruned trees where each pruned tree has one of its leaves removed. Something like this:
data Leaf = ... data Tree = Leaf Leaf | Branch [Tree] prunedSubTrees :: Tree -> [(Leaf, Tree)] -- [(the leaf removed, the pruned tree)] Any suggestions? _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
