title: What Regular Expression would Pass these Conditions?
body: <p>How do i write regular expression to pass the following?</p>
  
  <pre><code>LastName
  LastName SecondLastName
  LastName-SecondLastName
  LastName, F
  LastName SecondLastName, F
  LastName-SecondLastName, F
  LastName, FirstName
  LastName SecondLastName, FirstName
  LastName-SecondLastName, FirstName
  LastName SecondLastName, FirstName SecondFirstName
  LastName SecondLastName, FirstName-SecondFirstName
  LastName-SecondLastName, FirstName-SecondFirstName
  </code></pre>
  
  <p>At the same time, atleast the following should fail:</p>
  
  <pre><code>Any special Character (,?!#@%* etc) at the begining
  ,FirstName
  , FirstName
  LastName,
  LastName,Any special Character (,?!#@%* etc)
  LastName,FirstName
  </code></pre>
  
  <p>Basically, after a comma, there should be a space and alpha character(s)</p>
