bash - Repeat last command with "sudo" -

I often forget to run commands with sudo I get the last code to sudo I am looking for a way to create a bass function (or nickname) repeated with .

Any ideas?

  s () {sudo $ (history 1)}   
 Div class = "post-text" itemprop = "Text"> 
 You can type:  
  pseudo !!   
 (see.)
