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.

Sample Input 1

bac

Sample Output 1

Yes

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

Sample Input 2

bab

Sample Output 2

No

Sample Input 3

abc

Sample Output 3

Yes

Sample Input 4

aaa

Sample Output 4

No

Solution in Rust (1.15.1) (judge verdict: Accepted)

use std::io::*;

fn read() -> String {
    let s = stdin();
    let b = s.bytes()
        .map(|c| c.unwrap() as char)
        .take_while(|c| !c.is_whitespace())
        .collect::<String>();
	b
}

fn main() {
	let s = read();
	let ss = s.chars();
	let mut arr = [false; 3];

	for c in ss.into_iter() {
		match c {
			'a' => arr[0] = true,
			'b' => arr[1] = true,
			'c' => arr[2] = true,
			_ => ()
		}
	}
	if arr[0] && arr[1] && arr[2] {
		println!("Yes");
	} else {
		println!("No");
	}
}
