Problem 7 Write a function ap: ('a -> 'b) list -> 'a list -> 'b list ap fs args applies each function in fs to each argument in args in order. For example, ap [(fun x -> x^"?"); (fun x -> x^"!")] ["foo"; "bar"] = ["foo?"; "bar?"; "foo!"; "bar!"] where ^ is an OCaml operator for string concatenation. let ap fs args (* YOUR CODE HERE *) assert (ap [(fun x -> x^"?"); (fun x -> x^"!")] ["foo"; "bar"] = ["foo?"; "bar?"; "foo!"; "bar!"] );

Write a function
ap: ('a -> 'b) list -> 'a list -> 'b list
ap fs args applies each function in fs to each argument in args in order. For example, ap [(fun x -> x^"?"); (fun x -> x^"!")]
["foo"; "bar"] = ["foo?"; "bar?"; "foo!"; "bar!"] where ^ is an OCaml operator for string concatenation.
let ap fs args
(* YOUR CODE HERE *)
assert (ap [(fun x -> x^"?"); (fun x -> x^"!")] ["foo"; "bar"] = ["foo?"; "bar?"; "foo!"; "bar!"] );

Problem 7 Write a function `ap fs args` that applies each function in `fs` to each argument in `args` in order. For example, `ap [(fun x -> x^"?"); (fun x -> x^"!")] ["hello"; "world"]` should return `["hello?"; "hello!"; "world?"; "world!"]`. ```python let ap fs args = (YOURCODEHERE*) ``` [ieqiooxeqooy]=[eqooJ][ix<-x ung)&x <-x ung]deaesse
