Consider the following type of binary trees: data Tree a = Leaf a | Node (Tree a) (Tree a) A tree is balanced if the number of leaves in the left and right subtree of every node differ by at most one. Write a Haskell function balanced that returns whether a tree is balanced or not. balanced :: Tree a -> Bool

Consider an implementation of binary trees with Scheme lists, as in the following example:

Consider an implementation of binary trees with Scheme lists, as in the following example: Before proceeding, it may be useful to define three auxiliary functions (left T), (right T) and (val T) which return the left subtree, the right subtree, and the value in the root of tree T, respectively. (a) Write a recursive function (n-nodes T), which returns the number of nodes in the tree T. The following example illustrates the use of this function: > (n-nodes T)8 (b) Write a recursive function...
