Binary Int Tree Assignment

Motivation

Prepare for the Binary Search Tree Exercise with a simpler warm up.

int_tree

 datatype int_tree = NODE of (int_tree * int * int_tree) | EMPTY

Code to Implement

file:	src/main/sml/binary_int_tree/warmup_binary_int_tree.sml
functions:	sum

sum

fun sum(node : int_tree) : int =
	raise Fail("NotYetImplemented")

sum_accumulate

fun sum_accumulate(init : int, node : int_tree) : int = 
	raise Fail("NotYetImplemented")

fold_rnl

reverse order tree traversal

(*
 * depth-first, reverse in-order traversal
 * https://en.wikipedia.org/wiki/Tree_traversal#Reverse_in-order_(RNL)
 *)
fun fold_rnl(f : (int * 'a) -> 'a, init : 'a, node : int_tree) : 'a = 
	raise Fail("NotYetImplemented")

Testing
