Problem Set

2.  Give the general form of function declaration in ML.

Function declarations in ML appear in the general form
fun function_name( formal parameters ) = expression;

8. How is the functional operator pipeline ( |> ) used in F#?

The pipeline operator is a binary operator that sends the value of its left operand, which

is an expression, to the last parameter of the function call, which is the right operand. It is

used to chain together function calls while flowing the data being processed to each call.

9. What does the following Scheme function do?

(define (y s lis)


((null? lis) ‘() )

((equal? s (car lis)) lis)

(else (y s (cdr lis)))
