Using the type notation, write two oz functions for determining the sum of the elements of:
a) nested list, given by:
& λτ; nlist t& γτ; : : =
nil |
& λτ; nlist t> '|' & λτ; nlist t> |
t '|' & λτ; nlist t& γτ; (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)
)}
will display 14.
