I did it in 2018 in Elixir when José Valim, the language's creator, has publicly streamed his solutions [1] at mid-day (in Europe), so you had quite some time to resolve them yourself and then later watch him go through them.
I will be forever grateful to him for this opportunity.

This year I'm going to try to use Elixir, a language I've started learning the past year, hoping I can at least get past day 5 this year.
