"""Monte Carlo'ing Hillogram's Monty Hall Variant

Hillelogram on twitter came up with a surprising Monty Hall Variant: https://twitter.com/hillelogram/status/1175125663247998978

[BEGIN EDIT]

@hillelogram gives credit to this paper https://pubs.aeaweb.org/doi/pdfplus/10.1257/jep.33.3.144

/u/edderiofer on reddit pointed out that this is in fact the "Monty Crawl" variant from here: http://www.probability.ca/jeff/writing/montyfall.pdf
