Refactor find-substring example #39

Closed lassik closed 2 years ago

lassik commented 2 years ago

Returning the string instead of using display will produce the indicated "hello world" (with quotes) in a Scheme REPL.

lassik commented 2 years ago

The (string-length input) makes substring more portable; in some Scheme implementations, substring always needs 3 arguments.
