Problem 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.

Constraints

2 \leq |S| \leq 5

S consists of uppercase English letters.

Input

Input is given from Standard Input in the following format:

S

Output

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

Sample Input 1

BACD

Sample Output 1

Yes

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

Sample Input 2

ABCD

Sample Output 2

No

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

Sample Input 3

CABD

Sample Output 3

No

Sample Input 4

ACACA

Sample Output 4

Yes

Sample Input 5

XX

Sample Output 5

No

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

char *S[]={"No","Yes"};
char f;
char c[6];
int i;
int main(){
  scanf("%s", c);
  while(c[++i]);
  f+=i==4&&c[0]=='A'&&c[1]=='C';
  f+=i==4&&c[1]=='A'&&c[2]=='C';
  f+=i==4&&c[2]=='A'&&c[3]=='C';
  f+=i==4&&c[0]=='A'&&c[3]=='C';
  f=f!=0;
  puts(S[f]);
}
