Problem:
 Score : 100 points    Problem Statement Smeke has decided to participate in AtCoder Beginner Contest (ABC) if his current rating is less than 1200 , and participate in AtCoder Regular Contest (ARC) otherwise.  You are given Smeke's current rating, x . Print ABC if Smeke will participate in ABC, and print ARC otherwise.      Constraints  1 ≦ x ≦ 3{,}000  x is an integer.         Input The input is given from Standard Input in the following format:  x       Output Print the answer.        Sample Input 1 1000      Sample Output 1 ABC  Smeke's current rating is less than 1200 , thus the output should be ABC .       Sample Input 2 2000      Sample Output 2 ARC  Smeke's current rating is not less than 1200 , thus the output should be ARC .
