Sample Output 2

360

Solution in Rust (1.42.0) (judge verdict: Wrong Answer)

use std::io::stdin;
fn main() {
    let mut st = String::new();
    stdin().read_line(&mut st).unwrap();
    let x:i64 = st.trim().parse().unwrap();
    let mut result:i64 = 360/x;
    if 180-result < result {
        result = 180 - result;
    };
    println!("{:?}", result);
}
