title: Modifying White Space Elements From Element in Array
body: <p>I have the following array of arrays:</p>
  
  <pre><code>arr1= ["avd befe, bla, bla, bla, bla", "cveve devev, bla, bla, bla, bla", "aava beve. cavbr, bla, bla, bla, bla", "feve gyhyh, bla, bla, bla, bla", "ibtbt, bla, bla, bla, bla"] 
  </code></pre>
  
  <p>In my example, I am focused on the first group of characters in the array. These can include items that are of the format "x", "x y" (w a blank space between two groups of characters), and "x y z" (w two blank spaces between three groups of characters.</p>
  
  <p>I would like to delete the y from the third group of elements (so that "x y z" becomes "x z"). arr1 shown above is an example - the array I'm working with has a couple hundred entries. In that example above, I'd want "aava beve. cavbr" to become "aava cavbr" in the third element in arr1.</p>
