## Instructions

Objective
Write a OCAML assignment for the given questions of pattern matching and higher order functions in .

## Requirements and Specifications

Pattern Match
Exhaustively match all patterns of the following expressions using only the match keyword.
Y should match until there are only base types (int, float, bool, string).
A wildca (_) should be used to match the right-hand side of the cons (_::_) pattern.
Below are three examples that attempt to illustrate what satisfies our requirements.
WRONG EXAMPLE 1.1:
e: (int * bool) list
match e with
| [] -> …
| a :: _ -> …
Wrong, because a is a tuple which is not a base type so it must be matched further.
CORRECT EXAMPLE 1.2:
e: (int * bool) list
match e with
| [] -> …
| (a, b) :: _ -> …
Correct, because a and b in the pattern (a, b) are of type int and bool respectively.
