Double Each Character

Given a string, your task is to create a new string where every character from the original string is repeated twice. For example, if the input is hello, the output should be hheelllloo. This problem tests your ability to manipulate strings and handle input/output operations.

You need to read the input from standard input (stdin) and write the result to standard output (stdout).

inputFormat

The input consists of a single line containing a string, which can include letters, digits, punctuation, and spaces. The string length is at least 1 and up to 1000 characters.

outputFormat

Output the resulting string in which each character from the input is repeated twice. Ensure that no extra spaces or characters are added.

hello

hheelllloo
