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>
#define fast_cin() ios_base::sync_with_stdio(0) 
typedef long long int ll;
using namespace std;
const int MOD=1e9+7;
const int size=1e5+5;

ll a[size],b[size];

int main()
{
	ll n;
	string s;
	cin >> s;
	string x="AC";
	for(int i=0;i<s.length()-1;i++)
	{
		string y=s.substr(i,2);
		//cout << x << " " << y << endl;
		if(x==y)
		{
			cout << "Yes";
			return 0;
		}
	}
	cout << "No";

}
