title: A regular expression to for set of all strings over { 0,1 } that end with " 1 " and has no substring " 00 " in it?
body: <p>Like I said , I have this question related to Automata Theory..</p>
  
  <p>What would be the possible solution ?
  All I can think of is ( I know that might not be the solution..)</p>
  
  <p>( 0.1*.1 ) + ( 1*.1 )</p>
  
  <p>I know the " ( 0.1*.1 ) " part wont let me accept a string such as " 011101 " although it's a valid one , I need one more but only one 0 in it..
  Is there any better solution ?</p>
  
  <p>Thanks !</p>
