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.
Input is given from Standard Input in the following format:

If the judge can return the string AC
as a verdict to a program, print Yes
; if it cannot, print No
.

The string AC
appears in BACD
as a contiguous substring (the second and third characters).

contains both A
and C
(the first and third characters), the string AC
does not appear in ABCD
as a contiguous substring.
