Hello world

EASY

Hi! It is the first algorithmic problem, that created to learn how to work with the site.

First of all, find the input field with the name Solution. It's located below this description and examples. Inside this field, you should write your code.

Absolutely all algorithmic problems on this site require that your code get something from STDIN, process it, and put the result to STDOUT.

Let`s give an example. We should write a program that gets a line from STDIN, converts it to UPPERCASE, and put the result to STDOUT.

Example of code in PHP:

<?php
echo strtoupper(fgets(STDIN));

Let's copy it and paste in the code editor, after this press RUN button and wait until all tests will be completed.

Example #1

Input

hello world

Output

HELLO WORLD

Example #2

Input

yet one example

Output

YET ONE EXAMPLE
