Since the solution is O(1) time , so you can use faster input/output methods like BufferedReader or you can also write your own input/output methods.

P.S. Please don’t compare the time taken by C/C++ codes and JAVA codes. JAVA is approx. 2 times slower than C/C++. So, the time limit of problems is different for different programming languages.
