title: An efficient way that deletes specified characters from a string
body: <p>For example, given a str of "<strong><em>Stackoverflow is for every one</em></strong>" and remove of "aeiou",
  the function should transform str to "<strong><em>Stckvrflw s fr vry n</em></strong>".</p>
  
  <p>I have one char array of string: <strong>str[]</strong>  and one char array of chars to be removed:<strong>remove[]</strong></p>
  
  <p>My Solution: Loop str[] looking for each in character in remove[]. Shift str[] one place left every-time. I am sure better hack are possible. </p>
