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

use std::io::*;
fn main() {
    let mut s = read();
    let mut ss = String::new();
    for c in 0..19 {
        if s[c] == ',' {
            s[c] = ' ';
            ss.push(s[c]);
        }
        ss.push(s[c]);
    }
    println!("{}", ss);
}

// fn read() -> u32 {
//     let s = stdin();
//     let b = s.bytes()
//         .map(|c| c.unwrap() as char)
//         .take_while(|c| !c.is_whitespace())
//         .collect::<string>();
//     b.parse::<u32>().unwrap()
// }

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