<h2>FlatMapElements</h2>
<p>
  The Beam SDKs provide language-specific ways to simplify how you provide your DoFn implementation.
</p>
<p>
  FlatMap can be used to simplify DoFn that maps an element to multiple elements (one to many).
</p>

  <b>Kata:</b> Implement a function that maps each input sentence into words tokenized by whitespace
  (" ") using
  <a href="https://beam.apache.org/releases/pydoc/current/apache_beam.transforms.core.html#apache_beam.transforms.core.FlatMap">
    FlatMap</a>.
