Problem Statement

A balance scale tips to the left if L>R, where L is the total weight of the masses on the left pan and R is the total weight of the masses on the right pan. Similarly, it balances if L=R, and tips to the right if L<R.

Takahashi placed a mass of weight A and a mass of weight B on the left pan of a balance scale, and placed a mass of weight C and a mass of weight D on the right pan.

Print Left if the balance scale tips to the left; print Balanced if it balances; print Right if it tips to the right.

Constraints

1\leq A,B,C,D \leq 10

All input values are integers.

Input

Input is given from Standard Input in the following format:

A B C D

Output

Print Left if the balance scale tips to the left; print Balanced if it balances; print Right if it tips to the right.

Sample Input 1

3 8 7 1

Sample Output 1

Left

The total weight of the masses on the left pan is 11, and the total weight of the masses on the right pan is 8. Since 11>8, we should print Left.

Sample Input 2

3 4 5 2

Sample Output 2

Balanced

The total weight of the masses on the left pan is 7, and the total weight of the masses on the right pan is 7. Since 7=7, we should print Balanced.

Sample Input 3

1 7 6 4

Sample Output 3

Right

The total weight of the masses on the left pan is 8, and the total weight of the masses on the right pan is 10. Since 8<10, we should print Right.

Solution in Rust (1.42.0) (judge verdict: Accepted)

use std::io;
fn main() {
    let mut s = String::new();
    io::stdin().read_line(&mut s).unwrap();
    s.trim_right().to_owned();
    let mut ws = s.split_whitespace();
    let a: i32 = ws.next().unwrap().parse().unwrap();
    let b: i32 = ws.next().unwrap().parse().unwrap();
    let c: i32 = ws.next().unwrap().parse().unwrap();
    let d: i32 = ws.next().unwrap().parse().unwrap();

    if a + b < c + d {
        println!("Right");
    }
    else if (a + b > c + d){
        println!("Left");
    }
    else {
        println!("Balanced");
    }
}
