A count who is very sick and has no descendants to whom to leave his fortune, addresses his lackeys and says:
- I will bequeath all my money to one of you who gathers a number of gold coins equal to half the number of days I have left of life.
What would you do to try to get the inheritance?
What you should do is save a gold coin every two days. In this way, when the count dies, you will have the number of coins needed.
