Show message when unchecking everything and show other message every time I mark each check

How can I make a message appear when I uncheck all the checks and while it is marked one or more check shows another message

<label for="1">Checkbox 1</label>
<input type="checkbox" class="check" name="1" value="1">
<label for="2">Checkbox 2</label>
<input type="checkbox" class="check" name="2" value="2">
<label for="3">Checkbox 3</label>
<input type="checkbox" class="check" name="3" value="3">

$(document).ready(function() {

        $("input[type="checkbox"]:checked").each(function() {
             alert('check');
        });
       
 });
