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

use std::io;
fn main() {
	let stdin = io::stdin();
    let mut s = String::new();
    stdin.read_line(&mut s).ok();
    s.pop();
    if s == "abc" || s == "acb" || s == "bac" || s == "bca" || s == "cab" || s == "cba" {
    	println!("Yes");
    } else {
    	println!("No");
    }
}
