Write a "web application" that will display Hello World. The first one should be a plain HTML file without any code behind it.

Before going on do the above and then see the plain HTML solution.

Then pick your favorite back-end web development environment and write some code that will return the same HTML created earlier. Each soultion should have several versions:

1. Just return the string "Hello World!".
2. Return the HTML 5 version of "Hello World!"
3. Write version in which there is a template with a placeholder for "text" and the code fills that placeholder with the string "Hello World!".
