<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>
<p>In this task, we are going to implement a function that maps each input sentence into words tokenized by whitespace (" ") using
    <a href="https://beam.apache.org/releases/pydoc/2.11.0/apache_beam.transforms.core.html#apache_beam.transforms.core.FlatMap">
        FlatMap</a>.

<div class='hint'>Use <a href="https://beam.apache.org/releases/pydoc/2.11.0/apache_beam.transforms.core.html#apache_beam.transforms.core.FlatMap">FlatMap</a>
    with a lambda.</div>
