Problem Description

Xiao Z is participating in a competition. The competition consists of 3 problems. Upon correctly solving the first problem, a blue balloon (denoted as B) is awarded; upon correctly solving the second problem, a yellow balloon (denoted as Y) is awarded; and upon correctly solving the third problem, a red balloon (denoted as R) is awarded. These balloons are awarded immediately after solving each problem.

Xiao Z knows how to solve all three problems but may not necessarily solve them in the order of the first, second, and third problems. Given the sequence in which Xiao Z correctly solves the problems, output the sequence in which Xiao Z receives the balloons.

Input Format

A single line containing 3 integers separated by a space, representing the order in which the problems are correctly solved.

The input guarantees that the numbers are only 1, 2, and 3 and that they do not repeat.

Output Format

A single line containing three letters, representing the sequence in which Xiao Z receives the balloons. B denotes a blue balloon, Y denotes a yellow balloon, and R denotes a red balloon.
