Double Characters

Given a string S, output a new string where every character in S is repeated twice. For example, if S is "hello", the output should be "hheelllloo".

The problem requires reading input via standard input (stdin) and outputting the result via standard output (stdout).

inputFormat

The input consists of a single line containing the string S. The string may include letters, numbers, symbols, and spaces.

outputFormat

Print the string where each character of S is repeated twice consecutively.## sample

hello

hheelllloo
