Solution in Rust (1.42.0) (judge verdict: Runtime Error)

use std::io::Read;
 
fn main() {
    let mut buf = String::new();
 
    // 標準入力から全部bufに読み込む
    std::io::stdin().read_to_string(&mut buf).unwrap();
 
    // 読み込んだStringを空白で分解する
    let mut iter = buf.split_whitespace();
 
    let q: usize = iter.next().unwrap().parse().unwrap();
 iter.next();
    let mut lrt: Vec<String> = (0..q)
        .map(|_| {
                String::from(iter.next().unwrap())
        }).collect();
  
      lrt.sort();
      
      let result = lrt.concat();

  	println!("{}", result);
  	
  
}
