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 Ruby (2.3.3) (judge verdict: Accepted)

# 上皿天秤は、左の皿に乗っているおもりの重さの合計を L とし、
# 右の皿に乗っているおもりの重さの合計を R としたとき、
# L>R なら左に傾き、L=R なら釣り合い、L<R なら右に傾きます。
# 高橋君は、上皿天秤の左の皿に重さ A のおもりと重さ B のおもりを、
# 右の皿に重さ C のおもりと重さ D のおもりを置きました。
# 上皿天秤が左に傾くなら Left を、釣り合うなら Balanced を、
# 右に傾くなら Right を出力してください。
