This example of Stefan Karpinski comes from a [blog](http://julialang.org/blog/2016/10/julia-0.5-highlights) post highlighting changes to the `Julia` language with version `v"0.5.0"`, which added features to comprehensions that made this example possible.

First, a simple question: using pennies, nickels, dimes, and quarters how many different ways can we generate one dollar? Clearly $100$ pennies, or $20$ nickels, or $10$ dimes, or $4$ quarters will do this, so the answer is at least four, but how much more than four?
