How Does Santa Claus Deliver Gifts?

I hope this letter finds you well. I am Santa Claus, and I am reaching out to you with a small logistical challenge. We need to optimize the way we operate so that every child receives their gift in less than 5 hours. Additionally, we want to reduce the transportation costs of the reindeer and elves, who currently charge us 0.00001 USD per km for each gift they deliver. Could you help us determine the optimal number of warehouses and their locations? We would love to start by understanding the optimal distribution in the United States. We would greatly appreciate your collaboration. <a href="https://medium.com/@bauticoronado/how-does-santa-claus-deliver-gifts-cc0eaa64a5ae">Website</a>
