  <p>Preprocess an input text:</p> 
  <ul> 
   <li>delete punctuation symbols (commas, periods, exclamation and question marks <code class="java">,.!?</code>),</li> 
   <li>convert all symbols to lowercase.</li> 
  </ul> 
  <p>Then print your text.</p> 
  <p>Punctuation marks appear not only at the end of the input string, so you have to figure out how to get rid of all of them.</p> 
  <p><button class="btn-sm btn-outline-secondary" onclick="getElementById('hint-360').style.display='inline'"> Hint </button> </p>
  <div id="hint-360" style="display:none;">
   You can use the following way to remove the punctuation marks: 
   <code class="java">str.replace("!", "")</code>. Replacing a symbol with an empty line is the same as removing it.
  </div>
