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++14 (GCC 5.4.1) (judge verdict: Accepted)

#include <bits/stdc++.h>

using namespace std;

int main(){
	string s;
	getline(cin, s);
	int st = 0;
	for(string::iterator it = s.begin(); it != s.end(); it++){
		if(*it == 'A'){
			st = 1;
		}
		else if(*it == 'C'){
			if(st == 1){
				st = 2;
				break;
			}
		}
		else
			st = 0;
	}
	cout << (st == 2 ? "Yes" : "No");
	return 0;
}
