val find : (int -> bool) -> int -> int -> int

find p start beyond returns i with start <= i < beyond and p i or i = beyond if no index in the interval satisfies the predicate p.

val fold : 'a -> (int -> 'a -> 'a) -> int -> int -> 'a

fold a f start beyond starts with value a and folds the function f over the interval start..beyond.

fold a f start beyond =

     f (beyond - 1) (...  (f (start+1) (f start a)))
