Hi, I'm writing a couple of modules implementing a binary tree. Im proceeding adding a functions one by one becouse of checking with ocaml interpreter. Here...

I'm getting crazy {O.o} first of all a very beginner question: writing "let rec search x tree" is the same as "let rec search (x,tree)"???? (if not pleas...
I want to implement an operator "comp" which shall deliver the composition of two functions. I said let comp : ('b -> 'c) -> ('a -> 'b) -> ('a -> 'c) = fun f g...
... No, it is not. (x, tree) is a tuple, which is a single type/entity/whatever word you want to use. parenthesis and commas are not used in OCaml to...

Hi, I need to build a tree datatype defined like this: "type 'a tree = Empty | Node of 'a * 'a tree * 'a tree" How can I print all the leafs in this way? I...

We have to build a binary tree data structure for out software. And on the tree we distinguish nodes into either ordinary nodes or handles. type node = Leaf of...
