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

use std::io;

fn main() {
	let mut buf = String::new();
	io::stdin().read_line(&mut buf).expect("");
	let iter = buf.trim().split(',');
	let mut v:Vec<String> = Vec::new();
	for i in iter {
		v.push((*i).to_string());
	}
	let s = format!("{} {} {}", v[0], v[1], v[2]);
	println!("{}", s);
}
