problem_description: Statement
  
  Snuke built an online judge to hold a programming contest.
  
  When a program is submitted to the judge, the judge returns a verdict, which
  is a two-character string that appears in the string S as a contiguous
  substring. (The judge can return any two-character substring of S.)
  
  Determine whether the judge can return the string `AC` as the verdict to a
  program.
