Problem Statement

You are given a string S of length 3 consisting of a, b and c. Determine if S can be obtained by permuting abc.

Constraints

|S|=3

S consists of a, b and c.

Input

Input is given from Standard Input in the following format:

S

Output

If S can be obtained by permuting abc, print Yes; otherwise, print No.

bac

Sample Output 1

Yes

Swapping the first and second characters in bac results in abc.

Sample Input 2

bab

	uint8_t count[3] = {0, 0, 0};

	scanf("%s", S);

	for (size_t idx = 0; idx < 3; idx++) {
		count[S[idx] - 'a']++;
	}

	printf("%s", count[0] * count[1] * count[2] != 0 ? "Yes" : "No");

	return 0;
