Simple recursive solution: |
|||
<lang scala>def stepUp { while (! step) stepUp }</lang> |
|||
Non-recursive solution which almost gets away with not having named variables: |
|||
<lang scala>def stepUp { |
|||
def rec: List[Boolean] => Boolean = step :: (_: List[Boolean]) match { |
|||
case true :: Nil => true |
|||
case true :: false :: rest => rec(rest) |
|||
case other => rec(other) |
|||
} |
|||
rec(Nil) |
|||
}</lang> |
