Problem:
 ﻿Score: 100 points    Problem Statement  In 2020 , AtCoder Inc. with an annual sales of more than one billion yen (the currency of Japan) has started a business in programming education. One day, there was an exam where a one-year-old child must write a program that prints Hello World , and a two-year-old child must write a program that receives integers A, B and prints A+B . Takahashi, who is taking this exam, suddenly forgets his age. He decides to write a program that first receives his age N ( 1 or 2 ) as input, then prints Hello World if N=1 , and additionally receives integers A, B and prints A+B if N=2 . Write this program for him.      Constraints   N is 1 or 2 .  A is an integer between 1 and 9 (inclusive).  B is an integer between 1 and 9 (inclusive).         Input  Input is given from Standard Input in one of the following formats:  1  2 A  B       Output  If N=1 , print Hello World ; if N=2 , print A+B .        Sample Input 1 1      Sample Output 1 Hello World  As N=1 , Takahashi is one year old. Thus, we should print Hello World .       Sample Input 2 2
3
5      Sample Output 2 8  As N=2 , Takahashi is two years old. Thus, we should print A+B , which is 8 since A=3 and B=5 .
