Using the type notation, write two oz functions for determining the sum of the elements of: a) nested list, given by: : : = nil | '|' | t '|' (t is not nil nor a cons) b) binary tree, given by: : : = leaf | tree(value: t left: right: ) for example, the call {sumnestedlist [[1 2] [3 5] [3 [1]]]} will display 15, and the call {sumbinarytree tree(value: 2 left: tree(value: 3 left: tree(value: 5 left: leaf right: leaf) right: leaf) right: tree(value: 4 left: leaf right: leaf) )}
