Describe your change:

Added a solution to Project Euler Problem 203 "Squarefree Binomial Coefficients" Link.

The solution is based on three main pilars.

1. Calculate the unique coefficients of a Pascal's Triangle of depth d .
2. Calculate the prime numbers between 2 and the maximum coefficient Cmax using a variant of the Sieve of Eratos

Currently, when entering epic mode the README is frozen in the last level of the tower. When you're trying to fine-tune the score for a level other than the last one, it would be helpful if we had the README for that level available. The proposal is that when entering epic mode, the README is updated with all levels, one following the other.

Example:

# Starbolt - beginner

With the recent release of Phoenix 1.5 🎉 https://elixirforum.com/t/phoenix-v1-5-0-released/30693
Now is a great time to go through this example/tutorial with a fresh pair of eyes and completely update it (including) links to code snapshots. We can also extend it to include auth_plug #25 🔐 and presence #32 🚀.

• Checkout master
• Create new branch e.g: `update-t

Not sure what this would entail yet, but it would likely be a better way to reduce some of the boilerplate of opening an issue.
