title: Locate "LEV" in the String
body: <p>I would like to make a validaiton if "LEV" exist. The "V" is the last letter in a string.</p>
  
  <p>I'm looking for a regex that matches like this:</p>
  
  <pre><code>WATER LEV
  answer: true
  
  TTM DAB LEV
  answer: true
  
  FOODS IN2 LEV
  answer: true
  
  RLA LEV
  answer: true
  
  dd LEVFF
  answer: false
  
  RLA LEV 
  answer: false due to white space after "V"
  </code></pre>
  
  <hr>
  
  <p>This is what I tried, but didn't work:</p>
  
  <pre><code> LE*\D[V]
  </code></pre>
