Description

When you greet the intelligent robot and tell it your name xxx, the robot's input device will record your name and then respond with Hi, xxx. What's the matter?. This is actually the robot's auto-responder. Please design a program based on the robot's auto-responder functionality to output the robot's response.

Input Format

The input contains 1 line with a string $S$, where the string length $len$ ($1 \leq len \leq 100$) represents the name read by the auto-responder. The string is guaranteed to contain only uppercase letters, lowercase letters, and numbers.

Output Format

The output contains 1 line with a string representing the robot's response.
