WebIntroduction. If the left and right subtrees of a binary tree are mirror images of each other, the tree can be folded. An empty tree can also be folded. Because both binary trees have a left subtree that is the mirror image of the right subtree, they can be folded.. Approaches. Change the left subtree to its mirrored counterpart. WebYou can't really "invert" a binary tree. You certainly can define the same fold as above in a tail-recursive fashion, but it doesn't make sense to do that in Haskell or any other language without artificial constraints on stack depth, as it just trades stack space for heap space.
