Write a program that reads lines of input, and for each line, prints a single line with the output “Hello, X” where X is the text of the input line. As a special case, if the line contains the input “quit”, that signals the end of input, and the program should exit.

Example input:

Athina
Batia
Calliope
quit

Example output: (corresponding to the example input shown above):

Hello, Athina
Hello, Batia
Hello, Calliope

Hints and specifications: There should be a single space between “Hello,” and the text of the input line.
