Brew up some Elixir recursion

Recursion is recursion is recursion is recursion….

So how hard is it to go back to a programming language that you haven’t used for months that you only used for less than a year? Well, it took me a few more minutes than I anticipated, but in the end, I was succesful!

Tonight, I thought I’d take the simple idea of creating Pascal’s Triangle. A simple construction that creates a table of binomial coefficients for the binomial $(x+y)^n = x^4+4x^3y+6x^2y^2+4xy^3+y^4$. Notice the coefficients in our expanded binomial:
