Hello World的条件输出

描述

获得轿绝用户输入的一个整数，参考该整数值，打印输出"Hello World"，要求：

如果输入值是0，直接输出"Hello World"

如果输入值大于0，以两个字符一行方式陪帆姿输出"Hello World"（空格芦绝也是字符）

如果输入值小于0，以垂直方式输出"Hello World"

a =eval(input())

if a == 0:

    print("Hello World")

elif a >0:

    print("He\nll\no \nWo\nrl\nd")

else:

    print("H\ne\nl\nl\no\n \nW\no\nr\nl\nd")
