For this challenge, you will be playing a round-based auction game against all other participants simultaneously.

You start off with 10⁵ coins. In each round, you bid a number of coins. Everyone loses the number of coins they bid. The player with the highest bid wins the round and gets 1 point. We will play 10³ rounds.
