I was looking for programming challenges that I could use the Wolfram Language on other than Wolfram Challenges and Project Euler, and I found beecrowd, which has this beginner programming challenge named Hello World!.

Project Euler was getting too hard and I've solved most of the problems I think I can solve on challenges.wolfram.com, so I tried beecrowd, but unfortunately neither it nor HackerRank nor LeetCode supports the Wolfram Language. I've created a GitHub repository named beecrowd-work to store my solutions in the Wolfram Language.

Here are all the ways to print Hello World! that I can think of. Please comment if you have any more ideas.
